On the friends issue:

My ex was very extroverted; I'm not shy but more of an introvert. I lean towards nerdy intellectual friends; my ex would whine about spending time with them. I'm more flexible and can enjoy most social situations; he had stronger preferences.

As a result of all those factors and more, our social circle consisted mostly of friendships with "his" people. And after the divorce I eventually moved 30 minutes away. And although it was disappointing that so few of "our" friends reached out to me, the sad truth is, I don't really miss the rest.

I quickly met new friends through the adult rock band class that I started taking after he left. And deepened friendships with existing friends. I was free to go out and do things I liked, like go out to rock shows that my early-rising ex couldn't stay up for. And my current boyfriend always comments on what great people all my friends are.
