AITAH for feeling hurt about the things my girlfriend says and does?

Hi there,

I'm in a relationship with a girl that is perfect in my eyes, I love her with everything I have and intend to love her forever. She feels the same, we both need alot of reassurance from eachother.

She sometimes mentions things before we go to bed, or just after we had a great time together through call.

For example she will come over again on saturday and mentioned now that a friend is going to a protest, on the day she was supposed to be at my place. She didnt want to let her go alone so she decided to go be with her instead and then come back to me once she's done. I'm not sure if Im the asshole here, but I later voiced my opionion about the fact I set aside everything to make time for her, only to hear Im being treated like a side bitch essentially. And telling her that I would appreciate if she's more communicative about these things. I dont mind her leaving for a while, but it does sting.

She also mentioned the same day about how we met. We met through a dating app but she mentioned the reasoning being that a friend asked her to help gather data about men dating, and that I was one of those. Proceeded to call me a labrat, a research experiment but that she fell in love anyway. I was not happy with hearing that.

I actually met this girl before on this dating app, she had different images but it was the same girl. I spoke to her for about a week at that time, and then left her on read cause I wasnt interested in her. And when matching her again, she changed her demeanor which actually made me like her.

I never mentioned it to her cause it isnt relevant telling her now. She mentioned only having a few relationships, the longest one being with a very very bad guy. I will not go into details over. And for me it's the first time actually being in love with someone.

AITAH for bringing these things up with her, or should I have just kept quiet? ( I did phrase it alot lighter when I let her know )
