I think it's a bad idea to prolong a relationship that is inevitably doomed. If you know you would rather be with someone else, and you have the opportunity to make that happen, the best thing to do is to break up the existing relationship in as amicable a manner as possible.

Well, why wouldn't the girl and the guy, who she loves and loves her back, be together in the first place? Why would the girl be with a boyfriend? That might have a lot to do with whether or not this is ok. If the reason is that the guy is married, for example, then I'd definitely recommend trying to get over him. Or if the guy and girl live very far away from one another, then it's ok for her to have a boyfriend. I would NOT recommend telling her boyfriend that she'd rather be with someone else as hopefully that feeling would go away if things work out with the boyfriend. If the feelings do not change then it does not seem quite honest to stay with him indefinitely, though. I do think that MANY people think that each and every person should be in a relationship at all times. I have seen so many people do this - stick with a relationship until they find a new one (often by cheating), and I just don't understand this. I can't help thinking that if someone stays in a relationship knowing that it will eventually end, or that s/he SHOULD end it, that is a sign of real insecurity - it's like saying that you HAVE to have someone. I have never felt that way so that is why I've never understood it.

It isnt fair to the Boyfriend.

No one wins in a love triangle.That's bad Karma.Does she for a fact not love the boyfriend or does the other guy hope she dosen't love the boyfriend?She needs to be honest with herself and the other guys.Does the boyfriend know about this?If not I feel for him.I had a bf do that to me.He had a freind and dated me.Finally he dumped me to marry her.That stung for years now I am hurting over the loss of my true love another guy.Love has it's way.
