My boyfriends jokes are hurting my feelings am I overreacting?

I’m 29, my boyfriend’s 27 and we’ve been together about a year. Lately jokes he’s been making have been hurting my feelings and when I’m tell him about this it seems like my feelings are being disregarded.

He loves to watch and bet on UFC & boxing fights with his brother (29), they’ve been losing parlays for a while honestly and it’s been an ongoing joke that I’m bad luck because I’m typically there watching the fights with them when they lose. I didn’t take it to heart until about a month ago. I wasn’t with my boyfriend & his brother for the beginning of fight night and they actually were winning their parlays so far. I had plans on going over to join them later and my boyfriend calls me to say his brother says they need to keep their good luck going since they were winning and essentially tells me not to come. Ever since that happened the ongoing joke has really been bothering me. It feels shitty to be blamed for something that has literally nothing to do with me. Since that happened I told him I just won’t be around to watch fights anymore because it feels shitty being joked about like that. Instead of acknowledging how I feel my boyfriend said “lmao I be joking”. Like okay? It’s not funny to me.

Then more recently I told him I wanted to go to a concert with him that I knew he already planned on attending with his brother. My boyfriend “jokingly” said I’m not invited because I didn’t like the album the artists made. He literally said this like 20 times and tried to pass it off as a joke. And I do like the album I just don’t listen to it 24/7 like he does! So I went and bought my own ticket, now we’ll all be attendance and I’ll be somewhere on my own. Which isn’t abnormal for me honestly I’m not new to attending a concert solo but still. I told him that basically excluding me hurt my feelings and he again just passed it off as a joke.

Am I being overly sensitive? Please help

TL;DR it feels like my boyfriend continues to “jokingly” exclude me from things and it’s really hurting my feelings. When I tell him it hurts my feelings he laughs it off and says he was just joking. Am I being overly sensitive?
