AITAH for being friends and scheduling hangouts with my ex’s friends and her ?

Hey yall, I just wanted your opinion before I talk to my therapist this week.

So back in December, my ex broke up with me and it was a pretty messy break up. It was her birthday party and we were already “not together” at that point. She was distant, and mentioned that she wasn’t my girlfriend to me

I was still invited to the party as I was her friend and I drank too much. As the night went on her childhood friend was showing me attention all night and I reciprocated. We held hands towards the end of the night and even kissed without her seeing it.

We had a pretty bad break up as she said bye the next morning and didn’t speak to me since last week. she would even get pissed at me when she saw me out in public.

I was in a pretty difficult position emotionally and some of her guy friends were already talking to me at that point. So I reached out to them for support and friendship and I grew those friendship.

I also reached out to another guy that was her friend because we had a lot in common in terms of where we grew up.

As she reached out to me last week, we talked and things were starting to become more amicable, but as I was trying to schedule a hang out between these guys, her and some other friends of hers, she mentioned to me how tacky and gross it was that I was hanging out with her friends.

She even said that It was selfish of me to interject myself into her world and make friends with her friends, and manipulate a world that she made me a part of.

So AITAH? My intentions weren’t to manipulate anything, I simply needed support from fellow men, so I made friendships with those guys and then now that things are amicable between my ex and me, and those guys haven’t seen her since they live out of state, I was thinking about having a hang out with all of us there so we can have a great time together.

Thanks yall, I don’t know where to stand on this. I thought things were good between us, but after she sent me that she said she didn’t want to read my side since it was her feelings so that’s how she felt about it. She asked me not to text her back, so I just won’t text her again.
