I've been in a situation where a really good female friend (that introduced me to my wife) was interested in one of my best friends and I sat her down at the bar one night and tried like hell to explain to her the reasons NOT to get involved with my buddy. She has her own issues and he is NEVER going to commit to any woman as far as I can tell.
I talked till I was blue in the face and of course she didn't listen and thought she was going to be the almighty woman to tame the man that all other woman have failed to make happen. (Some woman just don't understand history)
Anyway I have known the guy since I was in grade school and the woman and I met under unusual circumstances back in the early 90's when I stopped drinking and she was a, to a certain extent, co-depedant ex-spouse to an alcoholic. We had a lot in common and a lot to talk about. Needless to say we helped each other through some of the worst times in our lives.
Well the inevitable happened and he broke her heart and I stayed the hell out of it because BOTH were good friends. It IS a conundrum of epic sorts when both are good friends.
Till this day he is still one of my best friends and she barely talks to me anymore. Go figure. But you know what ...... I TRIED TO TELL THE BITCH what was going to happen... But did she listen?
I guess my thoughts to you are this.....Either way YOUR F****ed in my experience.
Hope this helps.
