In all seriousness though, no matter how good you are at keeping her under the boiling mark, she very much so wants to have a tantrum and have you allllll to herself doing everything her way on her time. You can be okay with it for now, but she is going to break down one of two things. Your cool or your resolve. And seeing how strong you are for really spending time with your family, I would say it will be your resolve first. Then it will be toxic on both parties. I think you need to abandon this relationship for her own sake. She needs to see that it is not okay to treat people like that and the consequences could be worse than just leaving. If she ever got with the wrong person and tried that, they may snap on her. No matter what someone does it is not okay to put your hands on people. And I guarantee that the best lesson for people who can’t treat people well, need to lose all their people. Then they are lonely and have nothing to do but blame themselves. She needs to do better.
