But frankly, she told you point-blank that she doesn't want to come visit you so I would tell her you simply don't want to go there. You said you explained many times why (e.g. the area, family, the emotional toll on you). You don't owe her anything more. Just tell her straight up that you don't want to.

Bullies need to be told straight up 'no'. A clear, unequivocal, concise no. Maybe then she will get it.
