AITJ for Refuseing to attend my brothers wedding?

For context, I am a very sensitive person, and extremely impressionable, and I am not the brightest tool in the shed. This matters.

Anyway, so I have recently turned 21, and at my birthday party I had come out as lesbian to my family (my friends already knew), and they were all supportive. Exept my brother. We had always been close growing up, he used to help me out a lot and keep me on a good path, because like i said earlier, I was very impressionable growing up, and I had a few scares when it came to hanging out with bad people.

So my brother started getting toward my friends, saying to me later that I must have only said I was lesbian because ive been hanging out with them. I tried to explain that what he was saying was silly and its who I was, he said he "didn't buy it", and "forbid" me from seeing my friends again. Wtf? I wanted to call him an asshole, slap him and call him out to the whole family, but instead I cried, on my birthday mind you, and I stormed off, and I could tell my friends tried to follow, BUT HE STOPPED THEM, saying that it would be best if I was alone right now, but let family go past to see me.

Now back to the main part of the story. Since then, our relationship has been fragile and ive been really emotional over all this, but his wife to bee, was very unhappy with him and was on my side, making more drama. I was invited to there wedding, I was supposed to be his one of his wife's bridesmaids but I started to waver, but my brothers soon to be wife apologies on his behalf and I agreed to go. UNTIL the day of the wedding, where I arrived with a friend my brother had never met before, I had asked her to come because idk, it was silly but I just wanted a friend there.

But anyway, when my brother saw us together later, he told my friend to get out, he was dead set on the idea she "influenced me" into being a lesbian. My friend was goth, no hiding that, and I think he had some sort of link between her look and being lesbian, because all my other female friends who are not goth, he is typically fine with.He made a scene, but insisted my freinds was, even though, she spoke calmly, and never raised her voice. But my brother really got set off when my friend squeezed my hand, he saw it as us being together. In reality I was tearing up and she saw and was trying to comfort me. He threw a fit, and the commotion drew his soon to be wife out, and so he saw her dress and he was so furious.

I just left, my friend drove, and we went to her place and played video games and she comforted me.

The wedding still happened, but their marriage is off to a rocky start as my brothers wife is furious at him for how he treated my friend and especially me.

My family was devided about if I should have left the wedding and its caused a lot of tension, all the while my brother has made me feel insecure about myself, ant its something I am now struggling with that I wasn't before.

Am I the jerk?
