My girlfriend and I have been together for almost two years now. We've been best friends for over 10 years. We moved in together not long after we started dating and now we're in a very serious relationship and even considering marriage. I have a past history of mental illness and about 6 months after we started dating I began a slow decline into being very very mentally and physically ill. I was out of work for 4 months and was so sick I could barely leave the house. I was diagnosed with intermittent explosive disorder, severe panic disorder, severe anxiety disorder, obsessive compulsive disorder, night terrors, and post-traumatic stress syndrome. I've been getting better and better since I started on medication and I'm back to work and doing pretty good considering the shape I was in before. Nearly a year ago our sexual relationship started to change. This was before I even became seriously ill. We began having sex less and less often over time until now it's that we hardly ever at all. I understand that happens in relationships, especially in domestic partnerships, but it's not like her. That was the last thing I ever thought we would have a problem with in our relationship. As long as I've known her she's always been a very sexually oriented person. Our sexual relationship was very good before the decline. Over the year I've asked her multiple times what the problem is. She has given me a variety of different reasons each time I've asked her and now she says she doesn't know and doesn't want to talk about it. At first I thought she might be involved with someone else, but I can't see any reason to suspect her of cheating. She's changed a lot in other ways as well. She's lost interest in a lot of things we used to be interested in together. I'm still just as interested in everything I was when we got together. Other than becoming ill I haven't changed at all. Before we got together she was married for 5 years and eventually left her husband because of the same thing she's doing to me. That's what bothers me the most. She cheated on him a lot near the end of their marriage until she realized that she wasn't happy with him. She says she understands how I feel because I'm going through what she went through with her ex-husband, but she says she doesn't want to or sees no reason to try and make things the way they were. Every once in a while I think about leaving her but I love her too much and she's done more for me than anyone else ever has. I'm just not sure what to do or how long I should keep bottling up all my feelings about it because she won't talk about it anymore. I just keep all my thoughts and feelings about it inside. I don't have anyone else I could talk about it to. She's been in love with me for 10 years and has wanted to be with me all that time. Now she finally has me and a year into the relationship she stops making love to me. I just don't get it. Any advice or opinions are welcome!
