<human>: My girlfriend broke up with me nearly four months ago, and she said she doesn't know what it's like to be single, and that she didn't feel like a priority to me anymore. I'll be honest, both of those things are reasonable in my eyes as we're both young and I guess she wants to experience life/figure things out, and I have been rather distant lately because I took summer classes while she was 2 hours away at home and neither of us had cars to come visit each other. We rarely fought with each other, and when we did, it was always minor; no one ever yelled, and whatever conflict would be resolved quickly.

I'm losing my mind. The second reason given above seems clearly why she broke up with me, and it's tearing me apart. Knowing that I could have done something. I got complacent, thinking that she'd always be there. Now I'm here dying inside hoping I haven't lost my best friend for good.

We've texted a few times since we broke up. Conversations have been normal, like when we were together. There's no anger on either side. She says she loves me and misses me; a few nights ago she was drunk and called me 4 times while I was asleep at 3:00 AM and texted me things like "Please be awake, I want to hear your voice right now." Last night I was really sad/hysterical and told her that I love/miss her, she said the same thing back, but added "I'm sorry I stopped being happy." This false hope is killing me and I don't know what to do.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: gf broke up with me, says she didn't feel prioritized, still loves me, I'm sad/want her back
