Thank you so much for your reply! I kind of had "gone dark" for a could of weeks and that seems to be what brought on the sex last week. I guess I should have turned him down and kept it up, but I was weak, I really miss him. I know that is no excuse. Just to clarify one thing - that quote about the relationships with great sex vs those with bad sex - HE said that to me, that his cousin told him that. He said it immediately following our sex last Tuesday afternoon. I guess he is starting to question why our sex is so good to begin with, or maybe the sex he has with her is not satisfying to him and he can't figure out why. Not sure. I will work hard at going dark this time, and staying that way. I will be tested tomorrow night and every Tuesday night thereafter, as when I get home from school our daughter is asleep and he is usually laying on my couch watching tv or passed out. It is always so tempting to lay next to him and feel good for at least a little while, but I know in my heart that that will derail my long term goal. Thanks for the feedback!
