Hey man, it happens. Take this as an analogy:
You've been friends since elementary school, and suddenly, your best friends announces to you that he's gay. At first, you aren't too sure about what where how and when, and you're completely lost. Then, maybe a few days later, he says he has a crush on you. You,ve then got 2 choices.
"Cut him up" by telling him you're not interested, and try to stay friends with him as much as possible
Or simply run the heck away. (throwing him out)
If you get the analogy, it'S quite representative!
