I'm not 100% on how to act around her. I still love her and could easily fall back into acting like "normal" us. So I feel I need to keep my distance. Physically and socially. I would be happy with going dark right now, but it's impossible with the kid stuff. Any suggestions out there for me?
As I've said elsewhere, my heart goes out to all of you who have to interact with an ex while sharing custody of minor kids. A little easier for me since mine are grown and there's no real interaction necessary.
I think you have to do what's right for you without regard to how it affects her and keeps you on an even keel, and that's all that really matters as long as you're being polite. Only you will know what that balance is when you find it.
