I'm 28 Year Old Working Professional. Got Married To The

I'm 28 year old working professional. Got married to the person I love in 2013. I am not sure but post marriage I m not happy in a sense I get irritated on small things I cry on very small argument with my husband. THough my husband is very supportive. but I feel that there is something which keeps me depressed. One of the issue could be that though we are married however we still do not have a husband wife relationship, it is more like friendship. I m looking for reasons why I'm not happy?
