There's a girl that my friend wanted to get with, but I'm going to try the sleep of her.
Why do you want to sleep with someone your friend liked?
Because I like her and my friend should get over it.
You shouldn't sleep with someone that your friend likes because it will probably make him feel bad. It's not right to betray a friend like that. If you sleep with her then he might stop talking to you.
He got over it, don't worry about my friend.
He may have said that he got over it, I'm sure he holds some resentment toward you still. I would highly recommend not doing this in the future. You may have got lucky and is not that upset with you.
