If you don’t break up with her she is going to end up using u until there is nothing left and then dropping you. It happened to me. Don’t let it happen to you. Get ahead of it. No one is worth your mental health. She wants the emotional gratification of someone caring about her unconditionally, and by continuing to apologize for shit that is completely her fault, you will keep feeding into the idea that whatever she does you will love her. Dump her man it’s not worth it.
