I talked to him a few minutes ago. He chickened out tonight b/c "we are over at my house and I don't want her to have to make that long miserable drive home after." He also says he has too much work to do this weekend (he's in grad school getting a degree in counseling) so he'll probably wait til Wednesday when they usually stay at her place.
He did say he'll probably take my advice and use "mostly the truth"........ I quoted 33Girl and told him that he is an immature dolt. He hung his head and said "I know. I'm a bad person. I don't deserve her anyway. But I really want to get back together with (ex)."
So we'll see.
