Hello,
Thank you for writing to us.
Brief answer -
Every Relationship is built on Trust, your boyfriend never do that. Its better to meet once and clear things about varun(your friend).
Explained answer -
I would like to suggest to have chat with your boyfriend and clear things with him about varun.
I could not say that you are totally wrong at every stage, yes i thing at some stage you could be wrong with mentality of your boyfriend but at some stage he has to trust you.
Because even you dont have any friends as you said so definitely you should go to him and like to talk with him only but if he is not talking to you than it was not your fault i could say that because any one will do the same what you have done.
You should talk with him and clear this things, it may help for rebuild of your relationship if he could understand what you compromise till now for him.
Hope it will work for you.
Still if you need any more detailed guidance i will suggest to concern
psychiatrist they could help you definitely.
Take care.
Thanks & Regards,
Dr. Gaurav Prajapati
