Is OTHER wrong in the post ? POST : This is a throwaway because some people know my account.

Here’s the context. I got introduced to a friend, let’s call him A, from a close friend of mine and for a while, all the three of us did was play games and call on discord for a long time. But after a while, A started to call and talk to me outside of the normal groups and got closer to me, which prompted me to start to be a little more open.

At this point, I talked to A every day despite my wish to talk to other friends more. Then, A started telling me about how bad their life is and how much of a useless person they are. 

The mental state I was in was not optimal to be dealing with this, so I averted and tried to make them happier without stressing myself out.  Eventually it got out of hand and A was doing really bad, and I couldn’t even help them at first. One night I had to stay with them for hours to talk them out of something and it was clear that A was becoming slightly obsessed with me. Don’t think I’m just being a narcissist- A’s friends noticed his unusual behaviors as well. 

It eventually got to the point where A tried to drive a wedge between my SO and I. A started saying a lot of weird cryptic things and was in such a bad place that I couldn’t take it. At that point, he had messed with my head and my SO’s some and I went to our mutual friend to sort things out and he recommended I talk to A, which I did later on that night. 

A then days later cut themselves off from me completely after trying but failing to make me guilty. Later I found out from the mutual friend that A’s life wasn’t nearly as bad as it was cut out to be. 

I still feel like an asshole for turning someone in a very shitty mental state away like that, because I know how it feels. AITA?
