how do I tell a gay girl don't like her like that but as a friend

Okay, did she specifically say she wanted to go out with you? I'm not gay so I don't completely know how to go about this, but I'm pretty sure gays can have straight 老友记 whom they don't have crushes on and she'll probably understand that 你 don't like her that way if 你 tell her.

Just say "sorry but I'm strait .but I like 你 as s friend

All 你 have to say is "You're a good friend, but I'm only interested in guys." Don't worry, we 女同性恋 are quite understanding. And 你 can still be her friend, 你 know. :)

straight girls are gay
straight guys are lesbeans
:P

Like you'd tell a guy who has a crush on 你 but 你 only want as a friend. Be respectful, kind, yet a little firm when 你 tell her this.

Also, did she tell 你 that she'd kill herself? If yes; I don't see that type of statement has romantic, just a sign of needing some help. (Sorry for those who have told their bfs/gfs before)
