Girly girl,
You've got it together.
Seriously, you've accepted the things you cannot change.
You're facing the things you can change and are deciding what you want.
You know it's not about you.
You're realistic about who your AH is and who he's going to be.
Do what's right for you and your kids.
Being single really isn't that bad.
In addition to not having all the alcoholic crappety-crap to put up with, it's a pretty good life.
I was just thinking tonight, "wow, I wanted pancakes and green beans for dinner, so I had pancakes and green beans for dinner and I didn't even feel weird about it."
PM me if you ever need support. You know I'm single with a kid and in a similar boat on many fronts.
Always do the right thing.
K
