I'm going to ignore a friend who borrowed money from me but didn't give it back for 2 weeks
What makes you want to ignore him?
I'm starting to think that I'd rather meet new friends.
You better make sure finding new friends is what you really want to do.  Ignoring a friend is a good way to lose them as a friend since doing so is rude.  Only go through with that if you're willing to risk the friendship.
I have a friend who I'm going to ignore too.
I think that ignoring most of your friends is going to get a little lonely since ignoring them is a way to end a friendship. Your friends are going to think that it is rude if you keep ignoring them.
