Ask Dan & Jennifer

So my wife and I have been married for about 3 years, and I feel like she has no interest in me at all. I mean I know she loves me, but I feel like I have done something or that she thinks I am unnattractive. We will some times go for over a month without being intimate. She told me once that she loves me so much shes not interested in sex. I don't understand that being a man. The more I love her the more I find her attractive. It wasn't always this way, but it has steadily gotten worse. I don't even remember the last time that she took interest in our sex life let alone came to me when\if she wanted any. So I am getting to the point where I am starting to resent her for it, I mean I am really trying not to. But I can't help it, I feel like its always a different reason why she cant or wont that day. I don't need it every day (wouldnt mind though) but it feels like she looks at it like its an inconvenience. The other day she even suggested that I get a mistress, and couldn;t understand why that hurt me. I don't want other people I want her, she is my love not my lay.The issue that really comes out here is that she refuses to see a doctor or a psychologist or even a therapist. So I can only assume that she has no interest in "fixing" this issue. I feel so unwanted, I don't know how much longer I can do this. I don't want to have to beg her just to take an interest in us as an intimate couple. Especially considering that according to her she was inimate on an extremely regular basis with her old relationships. She also doesn't understand why talking about the previous boy freinds and lovers and her vigerous sex lif with them makes me upset. Please help......
