You have got to try and put that broad in her place. Clearly, you still love her. If you're remotely willing to stand by and take any of her garbage, you have to throw it back at her. Don't let her threaten you or walk out or anything like that again. If you can't just let her go, don't let her get the upper hand, eithe
Or, the next time she does something like this, then tries worming back into your life with sappy songs, just yell at her. She sounds like she needs it.
