<human>: So we had a good relationship but we were just too different. Didnt enjoy the same stuff, different personalities etc. And I'm starting a 2nd job and school full time in the fall so my already limited time will be non existent and I basically told her I didn't want to even try to stay together through it because we already have issues about how little we see each other.

I feel like I made a huge mistake though. I know that it's ffor the best because inevitably we'd argue more and more about my lack of time but is it normal to feel this much like a piece of shit? 

I care about her deeply but the physical attraction just wasn't there anymore and I feel like iI was trying to save her the eventual heartbreak and in doing so I made everything worse.

Could you distill the essence of the text into 1-3 sentences?
<bot>: I just broke up with my SO and I feel like a huge piece of shit even though it would have happened eventually.
