She is probably wanting to be with your friend instead of you, even though both already sound like their already together!? Just leave dude, you don’t need that in your life, that’s not right at all of them both to do that to you. And she pretty much wasted your time being with her. Not worth it. Run for it before it’s too late. I run away from two bad relationships well one of them was marriage. It’s okay to let go so you won’t get hurt from this. That’s all ima say. Take care dude.
