I'm going to ignore the friend who slapped me out of a crisis
Why would you ignore them then?
I don't need to talk to him anymore.
It's extremely rude for you to ignore your friend who helped you while you were in crisis. It's not easy to find good friends like that, so when you have one you should do what you can to remain friends.
I don't like my friend, he always take me for granted and now he slapped me.
Well, don't ignore him. Just tell him how you felt.
