Friend or Foe?

I don't think you're being selfish at all, you're respecting yourself and trying to distance yourself from someone who you don't like. If you've done all that you feel you can, then all you can do is wait for time to show if things will work out. If they work things out and get on well, there isn't anything you can do about it. If the relationship becomes abusive, however, then you must intervene for the safety of your friend. If he continues to disrespect you and your friend, you should talk with your friend and figure out whether or not you want to confront him. I hope it works out ^_^

your in a tough spot, you don't want to make your friend choose you or her boyfriend. First off you need to make sure you keep your personal feelings about him out of it, you aren't the one dating him and it's just not your place. but you said he has hurt her? like abuse? if so then you have a right to get involved but only based off what he has done to her. if i were you i would try and talk to your friend, tell he what you think of him and let her know your reasoning. in the end it's her choice and you should be there for her no matter how it ends up.

I don't think you're being selfish at all, you're respecting yourself and trying to get rid of the negativity from her bf if she wants to be with him and learn the hard way you have to let her and go your own way you have done your part as a friend and told her what you think maybe yall can talk here and there but hanging out wont be a good idea especially if he is going to be around.

You are not being selfish. You're protecting your friend. If her ex has made her cry before, and if he makes her cry now, you should tell her "Look, you cried about him before, you're stupid enough to go back to him, that's your fault. Don't come back to me, saying he hurt you again. It's your problem." A quote to live by: "You can cry once, but never cry again about the same thing. That shows you're weak enough to fall for it again." I think that quote fits perfectly for this situation. Personally I think you should confront your friend and talk to her about how it makes you feel him being with her. It's only going to get better if you speak up. Hope it works out well!
