What would you do?

She owes them nothing, they aren't even related by blood! Her only real connection to them is you, so I would let her know you are fine with her cutting all relations to them. She probably gave them those things out of love for you to make sure you had a place to grow up etc. If she still owns the property I think she should make them move out LOL...seriously, tell your gma you love her and it is ok for her to cut them off. She needs to stop communicating with them - they are toxic to her. I think she can do it with your strength to support her and if she knows you are ok with her standing up for herself. She needs to stop taking their calls etc...They sound like selfish bullies - well they can only bully her if she lets them..so help her stop allowing them this power over her!
