AITAH for breaking up with my girlfriend?

I (21f) broke up with my ex (21f) today. It was a medium length distance (4hrs). I live with my best friend currently, as she’s helping me get back on my feet. My ex and I were talking about moving in together soon, but first I have to replace my documents and ID due to them being stolen last year because I was homeless. I also needed to meet the landlord soon, and was fine with that. While talking about it, she said she would like for me to meet the landlord first, then come back to get my things and cats a week and a half later.. it’s an 8 hour round trip and long car rides hurt my body, so I said that it would be more cost effective and time saving to move my stuff the first time I went to meet the landlord. She kept fighting with me, saying that it would be easier to just come back for my things and cats, but I kept disagreeing. During these 3 days, I failed at getting my ID replaced because I need a second form of verification but can’t get it without an ID. That was extremely discouraging, and I went to her to talk about it and possibly receive a little encouragement. Instead, i watched her repeatedly be active on social media while not texting back multiple times, didn’t receive proper communication, and when I tried to tell her I was extremely discouraged and upset by not being able to get my ID, she wasn’t listening. So, instead i told her I needed space (which I didn’t receive) and went to sleep. When I woke up, I apologized for being upset, explained that I was discouraged and exhausted, and that i wanted to fix things.. we talked things out, or so I thought, but then she said she wouldn’t bring up the arguing, then brought it up again. There’s been multiple things over the last few months that have been bothering me, but those were fine. She, however, told me she was stressed and her trust in me wavered.. I’ll admit, I wasn’t good to her the first time we were together 5 years ago, but I’ve since gotten sober and went to therapy to be a better person, however she still uses our past against me, despite telling me she’s seen the change. I told her that any mistake was fine, that we could talk through it but her trust in me wavering was an issue because I couldn’t be sure that it wouldn’t happen again in a more stressful situation.. I also told her that it was messing with my mental health as well knowing that her trust wavered in me, and that my mental health isn’t something I’m willing to risk for anyone again.. Am I the asshole?
