Did I do something wrong?

Anonymous
Basically one night this guy friend of mine that I liked was hanging out with my group of friends for like half an hour and he brought a girl he met on tinder like only a week before and they were there doing pda all the time.
He knew I liked him cause I confessed months prior but he didn’t feel the same way, we stayed friends.
That night I was feeling like shit of course and wanted his comfort, so I “vent” to him about my sadness (like “why I’m not enough, what is it that I don’t have, yk that depressed stuff), I also told him first that that wasn’t very nice of him to do in front of me, but I wasn’t angry or anything, I was communicating my hurt.
He got really mad cause he said I crossed the line and I can’t get mad at him randomly, he has now deleted our whole chat and doesn’t want to be friends anymore cause he doesn’t want people in his life that brings drama.
Was I actually wrong? I don’t know anymore, so please let me know what you think.

(Hope this is comprehensible since English isn’t my first language)

That’s the point, he saw me as someone he could brag to even tho he told me he cared about me and that I was his friend, tho it’s true he never acted like it cause I was basically a therapist to him, but I chose to believe him cause I wanted it to be true really bad.
