Maybe, for now, you need to get her to agree that when she spends time with your daughter, it's on her own, with no OM present. At your current state, the "family days" are killing you. You can re-instate family days when YOU are ready and strong.

I think this is a GREAT, and prudent, idea.

My D's mother won't allow that (my D's mother isn't my W). She's not even keen on her having contact at all.
