Because of porn. He constantly watches it. Would rather watch it then have sex with me and that is not okay with me.
When I confronted him about it he said "that it's a habit that is hard to break". I've given him lots of chances to break it and go to therapy for it but he says no. That's like saying "you aren't worth it" to me.
ETA- I don't mind porn. It's the fact that he'd rather watch it then have sex with me and that he hides it. Hiding it and ignoring me when I want sex is the problem!
