<human>: We've been together for 2 years nearly 3 and throughout those 2 years we've spent mostly arguing over dumb things. 2 days ago we were on the phone and we had a bad argument about how she wanted to go one of her coworker's birthday to which he's a known cheater, in the end it ended in me telling all these horrible things which it ended with me saying that she can come and get her things. I sent her a text to call me so we could talk it over and to apologize for what I said, she didn't call me but I decided to call text her numerous times which she didn't reply to any of them. I tried calling her a lot of times to which she didn't answer and in the end she ended up putting me in autoblock, I also tried messaging her on Facebook to which she didn't reply either. I don't know what to do now and I'm really regretting what I said and I don't know what to do I don't want to lose her, she's the best thing that has ever happened to me especially since I'm a very negative person and she's the best thing that's happened to me these last 2 years.

It seems like I have to say what threw at her in the fit of my anger that I may have to explain better so I basically said things that happened in our past like how I spent a lot of money on her to the point I ended up broke, how she would text 2 guy best friends while ignoring me only to find out one of them was a guy who gave her some hickeys the same day we were supposed to go on our first date, how she wrote my bed or your bed to some guy as a joke and the guy showed it to me while at the same time the guy was showing it to everyone, how she had an STD but didn't know till we went to the doctor's only to find out she had it, how she was texting a guy behind my back and didn't tell me whatsoever while I would tell her if a female would text me.

Can you condense the text into a few key points?
<bot>: Argued with my girlfriend, said things I very much regret, and I don't want to lose her because she's the best thing that happened to me.
