<human>: Can you succinctly summarize the text in 1-3 sentences?

Long story short i started dating a girl last year around this time, or maybe a few months prior. We hit it off great, had amazing chemistry and i had some of the best times of my life with her!  I screwed our relationship up in november by getting drunk and sleeping with a previous ex [male]. She found out, we broke up. 

Just recently started talking to her again and realize now how much I miss her and us. She told me that she had briefly dated another girl in the months since we broke up and i found myself feeling jealous of that girl. They didnt work out, which i then felt relieved about.  Idk what to do and if i should even bring any of this up to her because we are talking again and thats a big step and im happy about it. Im not sure she'll ever trust me again, i mean i was the jackass who cheated so i wouldnt expect her to.

She reads reddit too so she may stumble upon this thread and figure out its me, which would be cool because im bad at expressing my feelings directly to people anyways.

After she found out about my drunken mistake she was actually willing to give me another chance then. I didnt take it because i also had issues with our relationship and felt i needed a break. I broke her heart and mine with one idiotic mistake.

Do i have any right to tell her how i feel or should i suck it up becuse I'm the one who made the biggest mistake and caused the breakup more so than any other little issues we were having that were fixable??? Please help idk what to do!!!!
