Hey all, lately I have noticed my husband is losing interest in sex with me. He rarely initiates it now and when I do he goes along but I don't think he's that into it. We have always had a pretty healthy sex life and he has always shown me that he loves and fancies me despite three children and aging. We are together 20 years and are in our very early 40's. We usually have sex twice or three times a week but it's been 8 days since we last had sex and he hasn't come near me since. I'm almost 100% positive he is not having an affair. His phone is always lying around and doesn't have a pin code on it so I know I could look at it whenever I wanted. He works in construction with males only so wouldn't develop friendships with female co workers. There is just something nagging at me though and I can't put my finger on it. I'm worried he might fancy someone else.
