I have fallen in love with a girl who has a boyfriend

[anachronistic]

it's okay to plant the seed, but don't *try* to break them up. if you try it, the girl might resent you.

Plant the seed and run.....

While i agree the boyfriend has no control over what choice she makes but the problem i have with this is theres no way to really test if her feelings for you are true or if she's only feeling this way due to the confusion of her own relationship.

I guess if you can accept this and the fact you'll be ship B than hey go for it.

Wait it out until she's broken up with her current boyfriend. Be nice.

Make sure she knows that you are a good friend.
Then wait. If it's meant to be, it will happen.

Know what? If she falls for you then it is because she likes you...not because you tricked her or anything. Girls aren't stupid or easily duped by others. They may dupe themselves sometimes, but if you are a guy and you think that you can put your moves on her....b.s. Guys are fools about this, thinking that they "made it happen." There's an old say, "A girl will run away just as fast as it takes her to catch the guy."

Or that equally old saying that guys do the chasing but women do the choosing (whether to stay or not). Its mostly true, IMO. Guys may be more reluctant to 'take the fall', but I think they are often more loyal to the relationship once they do. Some kind of 'clan loyalty' gene kicks in, esp when kids are involved.

We talked about it before, but the book 'The Red Queen' is an interesting book on the nature of human genetics & sexualty.

PS - Cam, I think your comments about stealing married women suck. Sacred things are only sacred b/c we decide to give them meaning, you know this.

To the OP - I'm w/Vash. A boyfriend is not a binding commitment. Its a testing of the waters to figure out what you want. It may be considered 'bad form' to chase another 'guy's girl' accordingly to some 'chest beating gorilla code', but that's just convention that has more to do with keeping guys from beating on each other too often, I suspect. But to chase someone who has taken vows and encourage them to break them is, generally, a pretty immoral thing to do. Assuming you value things like commitment, loyalty & vows. Not everyone does.
