<human>: Hi! About 3 months ago a girlfriend (18) of one year and some change and I (20) broke up after our relationship resolved into a bipolar mess of fighting and making up. 
We were completely commited and were in love the entire time but it just didn't work out. We both have firey tempers, and have clinical depression, and we fought 3 or 4 times a week towards the end of it and it ended after she went to strike me and I held her back, which she took as a violent act and left. I fucked up huge and it hurts every time I think about it. 

During the three months that followed, I went back to what I did in high school- smoked a lot of weed, went to clubs, and spent way too much money on stupid shit. 

This weekend however, I found myself alone with my thoughts and just broke down when I examined where i was going in life and called her up and asked her to talk. She has/had (I'm not sure at this point) a boyfriend but decided to come over and we snuggled and talked and some... 'light playing' engaged. (And now I feel like scumbag exboyfriend but I could give 2 fucks cause this new kid is a POS anyway)

We've been talking since then (i kind of have been in a dark place in my life since I broke down this weekend, as well as the fact that I'm quitting smoking, shes calmed me down from some serious freakouts in the last 3 days), and today she told me she wanted to break up with this new kid, and we got to talking about us, and I decided to get on reddit and ask what we should do. 

We decided not to date until she graduated high school and I'm fine with that but I still wanna forge a new foundation of relationship until then and actually seal the deal later but I need help doing that. I would love it if you all helped me cause this girl means more to me than anythign else right now. She's the light at the end of this dark, twisted tunnel that is being 20 years old. So thank you in advance

Can you give me the gist of the text in a nutshell?
<bot>: GF and I fought a lot, we want to rekindle, help me build a new foundation with this woman.
