I like this guy but..?

Wow, this is a little hard to follow but let me see so you're friends "crush" is into you? Well its an unwritten rule to not go for the guy that your friend likes just because its really not fair to her. I mean, imagine if she had done that to you, you'd probably be disappointed. The other alternative is to try and talk to her about it. Just mention something about him like "So, you and so-and-so, where do you guys stand because we've actually been kind of talking and he was interested in meeting up with me, i dont know if thats okay with you..." get her approval before acting because a friendship is way more important than a guy.
