I'm crazy. Aren't I?

La
The guy I like has a little crush on someone else. I'm just his best friend who is a female. Anyway I've been encouraging him to get her number and to get to know her. I want him to be happy. I guess I can't make him happy like that. Encouraging him to like someone is supposed to make me feel better, even though I don't want him to be with another girl besides me. My messed up thinking is that I want him to like this girl so I can be heartbroken and forget about him. We text like everyday as "best buddies" and I get upset sometimes. Im prob about to start my period😒 Maybe if he gets together with this girl, I can forget about him. I like him too much. It's so hard to be close to him but not close enough to his heart. 
For those who perservered reading this, thanks lol
