One of the problems he has with me is that he claims I'm "too controlling" (he says his parents and some of his friends have said the same to him).
Oh, I'm so tired of this one. It's #2 on the Cheating Spouse Hit Parade (right behind "NOW you've done it! (after you've exposed their affair) I WAS considering getting back TOGETHER with you, but now YOU'VE BLOWN YOUR CHANCE!", and ahead of "I need space."
"You're too controlling" is affair-speak for "I don't want anyone holding me accountable for my adulterous behavior," just like "I just need 'space' " is affair-speak for "I need space in which to conduct my affair, unencumbered."
