Nsfw just in case but I had to get this out of my chest and this isn't made up

So basically I'm in Winterguard and he's in regular marching and concert band. The teacher, went to school with my aunt and they're besties.

So basically he always says that I look like my aunt, and my ex would he like he's all red and would try to "flirt" with me and stuff on what people with crushes do but....................he would also get red when he saw me and treated me differently compared to other band kids and colorguard/winterguard kids

My ex boyfriend always said that he was looking at my ass and my boobs for some reason but I just didn't believe him. I always told him every time that he said something like that about the teacher I would say that he would lose his job

I mean also I would be doing stuff for Winterguard, for example a new toss or spin, and one of the guys from the team or staff member would help me with the toss and would actually ask me for permission to touch my hands. The teacher never did that

Band teacher also wanted me to do percussion but usually people there when they don't get something in percussion, he would go behind you and center you but obviously he would touch you and my ex was like telling me that he would touch you everywhere and if you were to do drum major then he would touch your arms.

Then he started telling me that bro had an erection, as he was holding his hand over his cock. But that's a guy thing and as a young woman who had no idea about these things I was just genuinely concerned comparing to how much he's been saying a lot about this teacher like gosh. Then he said oh I had a dream last night that you were smooching with him. I said: that's just genuinely messed up, I doubt that

My ex and I broke up because this crush on a teacher talk was getting too far and I couldn't deal with it anymore. Lol he actually told the teacher that I bet you have a crush on u/Ok_Long5367! (not putting my name here, sorry Reddit) And my ex got suspended from band

Whatever it is though the teacher and I remain close and my aunt (bestie) was at a football game for my school and we all just hung out basically

TL;DR: ex bf literally accused band teacher of having crush on me
