Question: My childhood is a divorce for 15 years of marriage with 10 yr old son and living independent. After 15 years (after our school) we came together thru a social media and very soon we came closer she proposes which I apprehended first due to her 10 yr old son and his closeness with her ex husband but she convince me that her son too will be accepting our relationship.
Now its been 7 months and she gradually disclosed some of crucial facts which is disturbing and also observed certain characteristics which indicates certain behaviour issues.
1.     She disclosed that she is having one more relationship with other guy and she slept with him, later said that was a bad day and now he is no more in her life later saw in facebook he is already there.
2.     Also she disclosed several affairs story she had
3.     She is hyper active over special platform and having very cheesy and casual gestures towards boys/men.
4.     She talk a lot about herself almost throughout the day over watsapp call and share her past and repetitively mentioning the same story over and over again.
5.     In most of the stories she glorifies herself, her father died 1 yr back she talks a lot about him and in most of the things/conversation she mentions him.
6.     Her friends talk bad and unethical about her once I heard them and inform her about the mishap, despite believing me she went to confront with her friends and reverted me and doubted my intentions and said you are having problem in your thought process.
7.     She never convince of my argument which is very logical which everybody else agrees/
8.     Whenever I try to show her the real picture she always ignores it.
9.     Professionally she got an amazing communication skill and go well. But here again too in her workplace too she is very much casual with her boss who were once her friend.
10.     She enjoys the status of explaining and convincing others.
11.     She is very very possessed about her son who is 10 yr old and really works very hard on his studies and takes very good care of herself.
12.     She usually says her friends are the priority in her life as they played a crucial role in her crisis.
13.     Spoken to her ex-husband, he just said he doesn’t have 1% trust on her, she usually lies and made her son lies too and always take some excuse to stay out of the house, she travels allaround the places outside the city too along with boss and few staffs where she stays in room sharing with boss which raise suspicion, high expectation from life compare him with others loud usually and things like that.
14.     She is very obsessed about me care about me shows lots of love for me and whole day she expect me to be hangaround with her over XXXXXXX and listen to her for long.
15.     Usually she put our call on hold/mute when ever her boss or any friends call her up which raises suspicion.
16.     She is very fond of cleanliness and orderly arrangement of things and feels very conscious on dirt and gets irritated if someone or even her sons spills over any dirt on bedsheet or anywhere in room.
17.     One thing is prominent she doesn’t refrain herself in sharing things with me rather her married life, love life of friends.
18.     Whenever she feels low she talks about ending her life and by morning she is back to normal.
19.     At times she is very difficult to understand, she portrays that she listen to me that too after blaming me “ Ok because this is the way you think which is not me, but I can do it for you”
I am confused, feeling insecure, cant trust her but she is very eager to get married.
Please guide me with the diagnosis of her as I am sure she is undergoing some psychological issues. And also as per diagnosis how to get away with the situation.

Thanks & Appreciate your detail indepth answer to my qwery.

While going through online on different types of personality of a person I tried making out that most of her behaviour are inlined with Narcissist person rather her behaviour of telling lies hiding calls messages her closeness with male friends and casual gestures and cheesy lines during their interactions, seeking self glorification and self importance and if trying to make understand anything didnt try to accept the flaws or gap in communication, during conversation she is very smart in convincing you or making such statement where you stop moving ahead and accept her opinion or words though easily one can make out that her opinion or thought process is so wrong. Her habit of interferring in other peoples life and their problem and feeling of winning on making them their suggestions in due course she didnt even realises that it is 12 O clock or 1 O clock at night she is on call with other person (friend) online, getting irritated on qwerying and dragging her past and her helplessnes and a statement like "No one has ever listen or understand her in her life"

NOTE:
1. Her separation too was very smooth with her husband on asking her the ground She mentioned that her ex is no more having trust on her and having an apprehension on her Profession n her habit of moving out or talking to any male person/friends and all.
2. Even I notice and observe that while talking to me first thing she talks lot much and repeated events of past without realising that she has mentioned it several time in her earlier discussion, in her conversation she mentioned that she is more comfortable with boys than girls since her early days as she doesnt like the typical girly nature of cribbing and all and so she has more male friends to whom she is comfortable with.
3. Always seek for emotional anchor so discuss all her ins and out with friends and friends are taking undue advantage of her emotion or devaluing her friendship there were multiple occassions I conveyed it to her that your friends are actually not worth sharing your every minute details they play mockery out of you but She on other hand never believes me and take it other way and cross it with them and later confronted in negative manner to me.
4. Though whenever she is there with me she looks committed but late over a phone she left suspicion as she muted me or hold the calls...
5. Her life become a trash due to a person with whom she is working and her ex wre having a problem but she continues working with him even after separation and she knows that person got an ill intention even he proposed her couple of times but she continues work and travelling eventually force her ex to suspect
and to take a call on it---even I have heard her over a phone shouting one day on some post of him on facbook and later talking in very shuttle manner with him but now she is planned to quit in coming months.
6. She is in cordial relation with her ex husband and the kid too is very close to his father though Kid is very sensible and cooperative and deeply attached to her mother and confirms to her mother that he is very much in support in her every desicion, kid is too good and very calm boy likes me too but still I amhaving apprehension that HOW AM I GOING TO TAKE OR AM I GOING TO HAVE SUCH A BIG HEART(handle the situation) his or his mother's involvement with ex husbands in future.

Though she says that working was a decision taken out of pressure as there was no earning member, at heart she is a homely person like to manage home and all and she would convince kid too and graduualy help n develop a healthy relation with him, though she mentioned her friends are the asset disconneting with them is not possible for her; even I dont want her to be disconnected but certain degree of line should be drawn.

These all raises a hue of suspicion-confusion-lack of trust and a fear of handling things and how it is going to affect me emotionally too as me too came out of a divorce recently where I have seen a very disturb marital like of one year as the girl was suffering from OCPD/EUPD/BPD.

So I am just taking time to settle myself emotionally but that doesnt change the fact of issues she is having. I am in a fix.
