<human>: Me and a girl started seeing each other casually, and I said I was not looking for anything exclusive or serious. Over time, we started to develop feelings for each other, but she still was not 100% trustful of me due to me seeing several other women in the early stages of our relationship.

Even though we did not try to define our relationship, we established that we were exclusive, and had told each other that we love each other, etc. Not a traditional relationship I guess, but for all intents and purposes, we were together.

One weekend soon after, I slept with another girl and immediately regretted it. I confessed to my infidelities, to which she (understandably) did not respond very well. After insulting me and swearing me off completely, I attempted to make things right with her. Over time, she came to fully love me again, and I am still in love with her. 

However, she still does not trust me. I don't think she ever will. I don't want to miss out on the college experience because I'm trying to convince this girl that I'm not cheating on her. We fight constantly, which she disagrees with and just says we are communicating about our issues. At least once or twice a week, she is left in tears at something that I have done that hurt her, yet she keeps coming back. 

I'm left with a tough decision - stay in a dysfunctional relationship in which we both love each other very much but with intense emotional strain, or cut things off and move on even though she is fighting hard against that option.

Condense the text into a few key points
<bot>: Exclusive with girl, I cheated. I tried to fix things, but am realizing that it's impossible to fix. Stay with the dysfunctional relationship or move on?
