NC. A close family member has a verbally abusive OH. He is fairly nice some of the time but has no problem having screaming, abusive, tantrums over very minor things (think "we ran out of milk" minor) and so we walk on eggshells whenever he is around. We have tried to go NC but it's like she is his hostage - any "bad" behaviour on our part is taken out on her so we feel trapped too. She has been talking about leaving him for YEARS, and she is very well prepared. She has plenty of places she could go, and she has been told many many times she could live with us as long as she likes. But she just can't bring herself to do it. Every time he turns "nice" again (which isn't even that nice) she seems to forget about leaving until he is awful again.
Is there honestly anything more we can do? This is miserable for the whole family. Sorry if I don't reply very quickly or give out much more detail - I don't want to give more away than I have to.
