<human>: Ok I know, im only 18 which I know is young but we're not all idiots all the time and I need some advice:

 * Background: Okay so I met this girl in 6th grade and always liked her but didnt start dating until 8th grade. Sure we had our ups and downs and at would get so mad at her but I loved her every step of the way. Ww dated all of the way though High school and into the first year of college. 

* Fast forward to my problem now: I thought she was cheating on me and instead of doing what I always do and talk to her, I panicked and isolated her and she though I lost interest in her. 

She called me crying and telling me that I was the one she was going to marry but in my mind I took it as her admitting to guilt and we ended up breaking up 3 months ago. Today I found out in that I was wrong and she had been faithful the entire time. 

She started dating a mutual friend about two weeks ago and I dont know what to do now. We both weren't ready for it to be over and I dont want to let her go. 

**My Question** Can I tell her what happened and how it made me feel and that I am so sorry and I never should have kept it a secret?
   
Im pretty sure if I called her now I would be able to win her back but im not sure if she will ever trust me again.

Can you give me a shortened version of the text?
<bot>: I screwed up big time with my SO by not talking to her and now I dont know if she will ever trust me again.
