Is EVERYBODY wrong in the post ? POST : This is my first time posting here, so bear with me.

I have my steam profile up on a website where you play the party game Mafia with other people online. One of my close friends on said website saw that I play a game that he also plays (terraria).  He contacted me and thought it would be fun if we play together. 

I am a big fan of this game, and he was a little bit new. I was teaching him some good tricks and was really having some fun, but I felt uninvolved when it came to actually doing stuff together in this game because he was actively avoiding wanting to do other stuff (such as bosses) with me.

We were doing one of the harder bosses. I was preparing for this fight beforehand and I admit I rushed it. I didn’t give him any idea of what to do in the fight. I just gave him some potions and expected him to roll with it. He dies immediately, and I finished the boss. He got passive aggressive and told me to log off, and that he would do the boss again by himself. I apologized and left. 

A few days later, he invited me to play again. I got on and was really excited to continue from where we left off, but he went through the next 25% of the game and expected me to be prepared for the next fight. I was sad and mad, but I didn’t let that be known. I asked if he had anything to help me catch up and that he didn’t. I was sad because I missed out on a big portion of the game when I was expecting to spend that portion with him. He told me to get some items from other characters and I got some at like 1% higher than what he was currently at.

He starts the boss, and after we finished it he sees a weapon I used to do well in the fight and calls me a cheater because the weapon I got was one boss higher than the boss we were fighting, but it was still at the same level we were at. He gets mad at me and says he’ll fight the boss again by himself. I got mad and said “I’m not the only one who can do shit by them self” and “You might as well do the entire fucking game without me” because of what happened earlier. I haven’t contacted him since.

I realize that it’s bad to get mad over a game, but I felt more mad at his actions rather than anything else. I really want to apologize because I realize that being petty is never the answer, but I want you guys’s opinion.
