I'm so glad you found this site before your problems became marriage-threating!!
H and I together 11 years/married 3/10 month old son. H had affair while I was pregnant/separated when son 5 months old. We had not had sex since we realised I was pregnant. H did not want to as he felt it was not right. If I'm honest though the lack of sex was a problem WAY before that. I thought H was not interested and I think H thought I was not interested.
Anyway Luvhubby sorry to hyjack your thread, its just that I came accross it and it started me thinking. Maybe I should post on this forum, it may answer some questions.
I hope it helps you and your H, I know I have had lots of support and advice over on Newcomers
