Your mother is manipulating you to stay glued to her side. You have a wonderful life and you deserve to live it. Move in with your boyfriend after you've talked with her about how much she means to you but that you're going to be putting up new boundaries. You may feel guilty at first but this will lesson and she'll come around and start finding new interests. She is relying on you to fill all of her emotional needs and that's not fair to you. You have a life apart from your mom. Good luck and best wishes.
