<human>: Could you distill the essence of the text into 1-3 sentences?

Me [23M] and her [19F] have been dating for a little over 6 months. We broke up briefly in early September for about two and a half weeks. We started out as a summer fling and I figured we would break up once school started because we were going to be 8 hours apart while we both attend college, this is something we talked about and pretty much agreed on.

Well when the school year started and we were both at our respective schools, she would ask every few days why I was still with her and why hadn't I broken up with her yet. It was annoying and the third time she did it I said something dumb, she got upset, I got upset and said if she didn't want to be together then we weren't together and that was the end of it. We didn't go fully no contact and against both of our better judgement, still did long distance fwb things, at her insistence.

Long story short, I missed her like crazy because I didn't really want to break up with her in the first place and then was too stubborn to go back on what I had said, so I wallowed around being sad about it, she on the other hand had relations with at least two other people, I only know of two for sure, she says because she missed me so much and tried filling the void with other people. I learned of one a week or so into us being broken up and then the second I learned about today, we have been back together for almost two weeks.
I know I don't really have a right to be upset about it but I am. She still talks to both of these people, and I know one of them knows we're back together but not sure about the second or if there are any others, nor do I want to know at this point.

I guess my question is how can I get past it and not let jealousy get the best of me? I know it wasn't cheating but it just feels dirty, she would still call me at night and sleep with me over skype and now all I can think about is her doing things with these other people then going home and sleeping with me.
<bot>: 23M breaks up with 19F, she sleeps with multiple people while broken up, now we are back together and I'm having issues dealing with my jealous feelings.
