and teach her to swim, whatever.

If she wasn't always trying to cause trouble at our house I would be fine with it.

Since DD comes home from there with a shitty attitude I don't want it to happen.

I suspect SD will PAS her out on me or attempt to. BM lives right around the corner so she's around too.

H is very offended that I don't want them around DD.

I sometimes wonder if he is trying to recreate the old family dynamic where he and D will make me the outsider and abuse me.

Thoughts? IMO neither BM or SD would be helpful to the sitch.
