It will be an interesting Thanksgiving, but mostly positive. I'm having dinner with a "friend family" which has sort of adopted me during this rather rough time.
In the time since she left, I have reconnected with my family, eat better, sleep better, watch less TV, play fewer video games, lost 30 pounds, gotten more fit, learned to dance, gained self-confidence, excelled at work, made new friends, learned to dress well, impressed at an interview, gotten a new and very exciting assignment, and even had another offer of marriage (to my great surprise, and of course I have refused). I will be moving this summer, so even if I lose the house, I'll be okay with that.
Of course, all this comes at the cost of losing my faith in the institution of marriage, my ability to trust, half my retirement (savings and pension), probably my house, and a great deal of happiness. And if I could have her back the way I remembered her--the woman I would have trusted my soul to, not the one who threatened "I'm afraid that if I stay with you I'll cheat, and I have four or five opportunities I can take advantage of at any time"--then yeah, I'd be tempted.
