WAW-I am by no means an expert and my advice is free and you gett what you pay for.
No disrespect intended, but you need to stand up for your rights. When she told you to move out, you did the right thing by saying no. Eat when and where you want. If she is so insistant on you not being around her, tell her to pack a bag. If you allow her to do this, IMHO, you are giving her all the power. Let your kids see who is being the adult and stable influence. Just my opinion.

Good luck.
