Couple of other things I remember from yesterday - she kept asking me what my family and friends thought of her. Major guilt is probably starting to sink in. Especially since she's pretty close to some of my friends.
Email from her this morning thanking me for talking, saying she really enjoyed hearing what I was doing, that it sounded like I was doing interested things that I was excited about, and that she hoped we could continue to be friends.
1) How did you answer her when she asked what your friends thought of her? I hope you would say "They think you're making a foolish decision," or "They feel bad for my pain," or "They don't know the details of our issues, but they ARE wondering why you wouldn't be willing to try to work on the marriage."
2) You and I seem very different, but I told my wife that "I have no intentions of being best friends with you if you end our marriage this way." If there is no infidelity involved, I do think parting couples can not only be civil, but be friends as well. But I don't know how one can keep their own personal integrity and remain friends with someone who ended their marriage by adultery.
