I plan on telling off my friend.
What has been going on between you and your friend? Is it going well?
It hasn't been positive. I did speak to others about him.
I'm sorry you aren't getting along well with your friend. But I don't think it's necessary to try and start more drama and let others see such things. Just keep it private to a few who you think can help you.
I don't like people who won't speak their minds and leave things unsolved.
It's totally understandable that you are irritated at your friend and I support you confronting him about the issue, but that doesn't mean you have to tell him off. Telling him off has a great potential for the friendship being ruined permanently.
