Recurring thoughts of her previous sexual encounters
I am a 28 year old male in a long distance relationship with this girl for 9 months now. I have known her most of my life and have similar circles of friends. We have an open, communicative relationship and she has told me about most of her previous sexual encounters. At first, this did not bother me that much, but as the relationship has become more serious, this has become a major issue for me. I have these constant recurring thoughts of her and what type of person she was before she met me. I have brought this problem to the table with her but she is not willing to discuss it easily and constantly asks me why I have these thoughts and why I have this opinion I have of her.
These thoughts have become overwhelming and I can't seem to get them out of my head which makes the problem even more severe. I could spend whole days thinking about this and this affects my mood and my day to day life. The other issue is that two of previous sexual partners I have to associate with and this causes me even more grief and makes the situation even worse.
I would like to deal with this problem as I really care for her and do not want to let this become the reason we have to end our relationship.
Please help, any solution, be it medical or other will be greatly appreciated
Thanks in advance
