My friend has a really serious crush on this guy, but I'm in love with him.
Why would you be in love with someone your friend has a crush on?
Because I can't handle my emotions that I have towards him.
This could end very badly. You two should not go after the same guy if you value your friendship.
I think she does have feelings for him, but she don't know, I'll figure it out after a few months
I recommend not sitting back in waiting for everything to happen. If you're actually unsure exactly how she feels you should talk with her about it.
