I'm the other guy in a love triangle and the girl can't go through with breaking up with her bf.?

She told me she would choose me, but changed her mind when she went to break up with him. She is afraid of losing me all together. Is it right for me to meet with the bf, whom I met once, and iron out a path for the two of them to be together and end this? Or meet even for him to make a decision between the two instead of her doing it? I'm not trying to persuade/dissuade him to choose something, nor will I tell him the full extent of the girl and I's relationship. I would tell him I was doing this as a friend of hers. I need this situation to end!!!!
