I would like to say that is because I am a woman of exquisite moral character (lol) but the truth would probably be closer to this: It was just not a time in my life that I came into contact with a lot of adults, let alone men. (sahm of little ones) So the temptation was there and there strongly but the opportunity never was. Would I have, if given the chance? Good gosh, I hope not. That was my worst fear and something that I am ashamed to this day that I even entertained. I felt SO vulnerable for so many years.
And when it all hit the fan, boy, was I angry at H. Now, our situation was a lot different than yours, so I don't know if that was a natural reaction or not. I suspect it is, though. It does sound like your H has both some legitimate resentment issues (for feeling rejected) and some major "projecting" resentment issues (Deb forced me into this). I think that the only way he can see the error of the second one, which is a pretty big error if you ask me!, is time. It sounds like he is struggling with wanting to take the blame and feeling bad about himself, to wanting desperately to push the blame off on someone else. The contact with OW can't be helping, either.
I sure hope he's leaving that damn cell phone at home while you are away!
Chin up, my dear. You have a golden opportunity to have a fresh start on this trip. Hope you see a lot more major league boners in the next couple weeks. (sorry just trying to get a LAUGH outta you!) I thought that line was really funny...
