<human>: Can you summarize the given text in a few sentences?

So basically I'm friends with this guy on steam and we talk quite a bit and being the super-safe-internet user I am I let him add me on facebook etc. So we would talk about anything really and we would talk about girls we like and so on quite frequently. So today he adds the girl I have a crush on on facebook and tells her this, and then unfriends her. In a nutshell i'm a kind of awkward guy and shes a popular girl so this will no doubt create super awkwardness/shitstorm,  etc at school tomorrow. So reddit, I've never met this guy in real life, he lives 800km+ away from me and I wanted to know if you had any tips on getting revenge in this situation.

(also, telling the girl he likes etc won't work as he doesn't really have any crushes/any he has told me about for that matter.)
<bot>: Internet friend tells girl I have crush on that I have a crush on her, now I need ideas on getting revenge on him.
