I agree with AnotherStander...that he is in the beginning stages of "love" and that can cloud one's judgement about the "realness" of this OP. My H is having an EA with OW and he claims he is "deeply in love" with her. There's really nothing you can do to convince them otherwise, so I would advise to "let it play itself out," focus on yourself (easier said than done, I know) & your kids,and GAL.
Really he's going to have to discover the person she is on his own. Meanwhile any contact with him should be upbeat & let him see your best side (which he originally fell in love with).
Good luck and hang in there...lots of support here!
