I'm with Jem-Fukuyama And I have deal with the same things to so don't worry every thing will be find and Jem is right and do as Jem says because that is the right way to deal with it. Skeloton4 here to help in any way and do any thing for you to help.

I haven’t dealt with it personally, but someone very close to me has dealt with similar. For the situation with others she might try to contact you through, I’d say make sure they understand you are doing what’s best for you and your mental health. You need to explain to them how she’s basically a user playing the victim, and that she will most likely try to pull similar things on them. If they can understand this, they might be able to be convinced to ignore her as well. Also, I’d have Moon help you talk to them, as they are Moon’s family, not yours, and they might be more willing to help protect you as their future in law and Moon’s future mate.

Unfortunately, family doens’t always listen, and will someimtes try to put the blame on you, saying you’re being too mean or not forgiving enough, but you can’t let that get to you. Stand up for yourself, and at the least, just tell them you’re not ready to forgive or whatever, and you don’t know if you’ll ever be, so please just drop it and let you work it out in your own time. That’s a lot easier and a lot less stressful than having to explain why you’re cutting her off over and over again. People who don’t agree with such a drastic decision are most likely not going to be swayed. Hopefully your soon-to-be in laws are more supporting than the family from which I derive this advice. They might even be able to provide some insight on this sort of situation too, since life is often hard and you sometimes have to “let people go” from your life.

WIshing you luck and peace!

My best friend is going throigh this with both her parents right now, she moved in a rental house with our 'pack mother' (The one who bails us out when dung hits da fan.) She has cut off connections but they know her friends contacts since they took her phone. They have been tryin to call for awhile, my friend told me that this was likely and to either ignore it. That must have did the trick since they haven't messaged us in a few months. She will be a legal adult in the spring and she wont have to worry anymore about her manipulating and abusive parents. I suggest warning people who have contacts with them and explain the situation, if you stay strong, your mother will give up eventually, like most bullies do if they get nothing from their efforts. I also suggest to ask for help from others who can help if your feeling insecure. This have been a literal lifesaver to some of my friends. Hope you get through this!
