I don't know what I am.

For the longest time, I've always thought I was bisexual. These feelings of attraction towards boys started in my middle school days. But I also did like girls. Being in relationships with girls were always so awesome and comforting. But they would always end with me getting my heart broken. With this in mind, I've recently started thinking that I'm fully gay. I know it's a stupid reason, but I feel like my relationship trauma with girls over the years have just completely killed off my interest in girls. But at the same time, I'm having a really hard time with labels! Like, what if one day I find a really amazing girl that actually cares for me and I change my mind? If I still find girls pretty, would I still be gay? Idk I've just been so confused lately but I'm really glad I have a place where I can say all this without much issue :D
