Girls do I have some tea for you

So me and my ex broke up a month ago. He wanted to stay friends so we became friends again (just saying this HE wanted to stay friends with me I didn't care if we were friends or not). It's been a few weeks and we had a disagreement, I told him to sit somewhere else (We sit together at school with our friends), he didn't want to because he wanted to sit with HIS friends (who I have known longer than him and they like me better than him) but I wasn't in the mood for his shit, so I sat with another group of people. We figured out the disagreement, I sat with the group again another few weeks pass and he stops talking to me (just reminding y'all HE was the one who wanted to remain friends), one day only one of our other friends was at school that day, I had to stay late in my class so it would have just been my ex and our friend, I got let out of my classroom and went to our spot and our friend was lonely, my ex wasn't there so I sat down and saw my ex walking around with the one group of people he knows I hate with a fiery passion, he looks at me and just keeps on walking away, when I confronted him about it later he said he didn't sit there because he didn't think I would be at school (I was late because I got my braces off) like sis no you left out friend alone (he has anxiety so he isn't good around people he doesn't know or when he is alone), my ex knows this but he didn't want to sit with him because I wasn't there like no sis I had to sit somewhere else once because you didn't want to leave your "friends" but when I'm not there you won't sit with them and I thought he wasn't talking to me. He said I was complicated but sis no he is the complicated one.

Sorry this is really messy it's midnight and I have taken medicine that's making me drowsy but I had to spill some tea otherwise I would have had to keep bottling it up

Thank you if you actually read this

Also I found out today that he is now dating someone who he met up with when we were dating and I have this really strong feeling that he was dating her while we were dating I don't have any evidence yet (I just found out today) but I have an extremely strong feeling
