Set boundries and stick with them no matter what. As for taking Olivia, if I were in your shoes, no way would I allow him unsupervised visits with his parents or by himself.

You may think he is not a danger and would never do harm, but the news reports are littered with stories of how a divorce situation turned tragic in regards to the children. From what I've read of your saga, his mental state is not stable, and thus I believe you should not trust him to take Olivia out of a controlled environment.

As for your Mom, how sad she cannot be supportive in a healthy way. It will be good when you can move out to be on your own again. Hang in there and be careful of what you allow him in privileges.
