I'm upset at my crush/good friend for going on a date with someone else
You don't want him to go on a date with someone else?
Yeah I want to be on that date with him.
If you want to date your friend you need to tell them and not sit in jealousy. It is also rude to try and impose on someone who is not interested in you.
Uhh, are you saying he doesn't like me?
I'm not saying he doesn't like you. I'm just saying that if you talk to him and find out his feelings aren't mutual, then don't you think you should just let him date whoever he wants?
