mk,
You're right. Single is tough as you get a little older. I'm 52, and don't look forward to dating, or "hooking up". I really am "relationship centric" Don't get me wrong, after 3 months in Iraq, and 4 years of celibacy, some gratuitous sex would be great, but wouldn't make me feel better about anything. Single with kids is anger-producing (to me) because you walk out on a group of people, ususally without a strong enough reason to do so. The "I'm unhappy bulls*it" doesn't really cut it for me. As nephartiti says: "I lost a whole family" I get it.

I guess that you have to be really unhappy to sell your family down the river, and say thet "They're resiliant". Kids aren't plastic.
