Breaking up... 💔

I was with this guy for like almost 7 months, I gave him my virginity & I really did love him. He gave me a promise ring & told me I was the one he wanted to marry & that he was done searching . Around our 4 months we had been arguing everyday & I was very optimistic bc I want to make things work & I want to fix things. But he was very negative about it. I had invested a lot of myself into him but I still had a hard time trusting bc he wouldn't do things to gain my trust. He'd say hurtful things & he wouldn't think about me as much as I thought about him when it came to just doing things. However I was still willing to make it work. But it came to the point where I was begging & pleading with him to give me his time & his affection. When I would come over he would want his "me time" but we were long distance so I didn't understand how he wanted me time if I already wasn't there in the first place . & that was already hurtful as it is. But later we had discussed that we were having problems & I would see him on last time but he wouldn't give me any affection if I were to go so I said no & then the next day he broke up with me. Basically told me that he didn't love me & it was a mistake . He said that our relationship was too toxic for him. & that he's already close with some coworker at his job . I'm just confused & hurt.. Does anyone have any tips on getting over a breakup?
