My friend was talking to the girl I like so I stabbed him in the back...figuratively.
Was your friend trying to get together with your crush?
No, but I was still jealous of him talking to her.
You can't expect to keep your friends if you backstab them. You should place more importance on your friend than this crush of yours.
I just need to show him that I'm mean and I don't care about him anymore. I want to ruin his life.
It sounds like you aren't a very good friend if you are picking a girl you are not even with over your friend. People are allowed to talk to each other without someone over reacting.
