I'm thinking of cutting my friend out of my life. Sorry if this is really stupid. It's just after everything, I'm not even sure if I'm being an asshole or if I'm justified in behaving this way. Everything's just really really confusing and painful
What is your number one reason to cut off communication with your friend?
I don't want to be his friend anymore.
It sounds like you were hurt by your friend.  It is okay to stop being friends with someone who doesn't treat you well.
I guess. I just don't know for sure.
Well you can take some time to think it over. There's nothing wrong though with ending a relationship with someone who you don't want to be friends with anymore. If you want to try to keep the relationship, talk to your friend and explain what about them bothers you so they can maybe work on it.
