ok i have girlfriend and i have a friend who've i known for a while ok she told me a was a goodfriend like her best friend so i found out that she wouldn't go out with her guy friends like im her friend so i cant go out with her or any other firend of hers so i drop small hints that i care for her and shes says stuff that makes me feel like she has feelings but i dont know she also knows i have a girlfriend so im not sure what to do? what do i do? i talk to her on yahoo messanger sometimes.

UM....
throw a brick into her windows with a threatening letter around it

uh, you have a girlfriend. so this shouldnt be a problem.
if anything you breakup before you move ahead with this "good friend"

does your gf know about your feelings for another girl??

well first off, you might wanna try some punctuation. i couldnt' tell when your sentences ended and stopped. anyway...

if you have a girlfriend and have feelings for a different girl... then that's really sad. you should tell your girlfriend that you dont' have feelings for her, unless you have feelings for both of them... if you have feelings for both of them, then simply just forget about this other girl until you and your girlfriend break up. however, if you don't have feelings for your girlfriend, then break up with her and then wait a little while. try to figure out if this other girl likes you... like from her other female friends maybe? idk... just look at all the hints... try to analyze it all. and if you think she likes you, then ask her out.

well no she doesnt but she knows that te other gilr is my friend so yeah i know her myself so i really dont have to find out by her friends so yeah i dont know what to do

You should stick to your girlfriend now..since your goodfriend says she doesn`t want to date her guyfriends.
