AITA for hating the fact my friend is friends with my ex?

God I’m so scared they’re gonna see this.

But for context, the relationship started off great. We had a ton of the same interests. Then things started to get messier and messier.

I have bipolar disorder, but never had to go to extreme lengths to get extensive help because it was manageable. The manic episodes and the depression episodes were evened out.

But the depression episodes started to escalate — the manic episodes, not so much. The episodes got to the point where I started hearing voices.

And the episodes didn’t get that bad until me and my (now) ex partner started having really bad arguments. They would start the arguments over something small and petty (having celebrity crushes, me being friends with other males, etc.) and they would manage to spin the argument around, make it my fault, and make me apologize. But when my issues were brought up (me being uncomfortable with the polyamory) it got brushed off, making me feel useless and unseen.

Not only the arguments, but also the fact they gave me their prescription drugs (that I am not prescribed) to “fix” my depression episodes. Which yes, did temporarily pull me out of an episode. Temporarily. But it would come back worse, and I’d start hearing voices and having more extreme bad thoughts. Then they tried putting me on a diet to “fix” my IBS. Which was a bit triggering because I openly spoke about having an ED in the past, so diets are a touchy subject with me.

They also tried to sexually gr00m me. Everytime we had an argument they would come over when I told them not to, and we’d do it. I was always at a yellow light. But that conditioned me to start thinking they were the solution to my depression episodes, even though they were partially the cause. Most of it was just chemical stuff.

The day we broke up. Hours before, I was on FaceTime with my friends, having a mental breakdown during my lunch at work because of how miserable I was in this relationship. That friend was on that FaceTime. We FaceTime as I’m driving home, and my ex partner is there when I told them not to show up. That’s when I decided to break it off, I felt that my boundaries were overstepped.

They follow me into the apartment complex, and is standing outside of the door into my unit. I’m breaking it off, telling them to leave, and shutting the door. They try to enter, and I immediately close the door fully — scared for my safety, because they’re always strapped.

Not that I 100% think they would hurt me, because I did have trust in them. But then again, it’s like…you never know with people.

I’ve never hit these kind of lows in my life until they came into the picture.

And today, I found out that friend is still in contact with them without me knowing. Their excuse is that they “wanted to see both sides”, but in my eyes, all I see is that they’re friends with my abuser.

They did not know each other until we started dating. AITA for considering ending the friendship?
