avoiding sex

It's not that I don't want it...because I do. But for some reason I just can't. Found out over the summer that my husband had been cheating and all of a sudden, all my feelings on the subject are back and worse. Maybe it's just the hormones, but I can't fathom the thought of him touching me. Idk. Every week my doc says I should be having sex to get this baby out and I want to cry every time she says it. Ugh just venting I guess.
