I (19 f) have a friend group that goes to a different college in another city. This is because of one of my close friends going there and as I visited I got closer with everyone in the friend group she had made. I'll call her S. In October of last year the entire group went on a trip and rented a place for the weekend, on the trip I ended up hitting it off up with a friend in the group (20 m) who ill call J for anonymity. We talked for around 2 months after that with me visiting him spending the night multiple times at his place and we went on a date since we wanted to get into a relationship. Anyway, that didn't end well, he wasn't over his ex and was very dishonest and disrespectful which led me to end things with him. I visited S again in February and the entire group hung out, I pulled J aside and that conversation also did not end well as I was not over him and found out he was completely over me. I should've known since it had been 2 months but I was in denial about it i guess. However I have been over the situation for about a month now and I found out that J is now dating another girl in the group, ill call her R, who I am semi-close with however she is closer with other people in the group. I'm not really sure how I feel as i know that there was no feelings there when me and J were going out, however it makes me a bit uncomfortable. I told S this as she's the one who told me what was happening and she said I was being a bit of an asshole. I get that me and R aren't the closest in the group and I am over J, but i'm also not mad at either of them or expect them to stop seeing each other. I am purely just a bit uncomfortable as me and R are still friends and she knew how hurt i was over J's actions. I guess I just need another opinion on if im the asshole or not as i'm a bit confused on if I have the right to be uncomfortable. Aitah?
