The good thing is that you are an adult. She can't come to your house, pack your bags and make you move. For the time being it doesn't sound like crossing the country by plane is even a good idea due to COVID, anyways, so you are off the hook for now.

I'd use this time to work on preparing to set boundaries with her in the future. There is plenty of reading you can do online about this topic. If you have a therapist, this could be something to discuss with them too.

I live far from family and have my reasons. I definitely understand that.
