so my best friend, I’ve known since was in first grade has been seeing this guy…And everything was fine for awhile until weeks and weeks went by and I noticed a change in her behavior. She was very unhappy because of his suffocating and jealous nature…he would be very aggressive when she would try to end things, and kept asking me to tell her what to do. Which of course I said to breakup because that seemed to be a horribly toxic relationship. And even maybe I said to breakup also a little selfishly because she was my best friend, and I feel like we were becoming very distant because of how much time she was spending with him. She eventually ended things a couple weeks ago with him….And he then started texting me about the situation and he ended up just basically insulting all the struggles and insecurities I have because I told him he’s.has issues he needs to face….Today I found out she’s back with him, after all the things he said to me and has done to her. I don’t want her out of my life, but I can’t stand him any second longer. What should I do? I’m stuck.
