Advice on love?

(Using falses names but actual situation) A year ago I was dating this guy (Jason), and we had an amazing relationship. Although unfortunately our relationship took a turn during the summer. It went quiet and I’d put my effort into talking to him or we’d have no conversation, in other words he wouldn’t contact me. Although regardless of no contact from him, it was still obvious he loved me a lot and he still did a lot of things for me. Then when we back to school he just went completely distant and no conversations then he broke up with me after my birthday. I was heartbroken as we were each others first love and I found out his friends were spreading rumours about me. Fast forward to 2 months after our relationship ended, I started talking to this other guy (Carlos) and I realized I didn’t want that so I ended it with him after 3 weeks, as for also he was cheating on me with his girl bestfriend. A week after that me and Jason somehow got in contact again, he told me he had been sad when he saw me with Carlos. Me and Jason had a nice conversation found stuff out from then, then he randomly turned cold and told me to get away from him. I couldn’t take it how he treated me so I gave him a letter regarding all my feelings and how I still liked him. We didn’t talk after that until 3 months after when he followed me on instagram. We got in contact again and it was a good friendship although he was yet, cold again without a reason. He completely ghosted me so I just left him alone, then this guy (Dylan) asked me out and he was one of my friends so I just said yes. I really did love Dylan although he again did cheat on me. We were together for 3 months but now it’s been 2 months since him but for some reason I’ve came to realize I couldn’t get heartbroken by anyone except Jason, I don’t know what my feelings are and I need advice on that, and I need advice on Jason. Please be honest, even if its rude!!
