So, what your saying is that you would go out with her ONLY because she likes you, and not because you like him, you only have feelings for her in a friendly matter, and don't want to distroy your friendship that you have....

Well...if thats the case, you shouldn't ask her out, definately not, if you would be asking her out just because you think that she likes you and not the other way around don't ask her out....just wait for her to ask you out, IF she asks you out, don't stuff the friendship.

Sorry matey, got a bit confused with ya, thought that you liked her in ways other than friendship
