Ex advice

My boyfriend and I were together for almost two years. About a month ago, we broke up over a petty argument. Three days later, I reached out, we talked, and got back together. The next month was kinda rocky but mostly good. Ten days ago (Oct. 17), while trying to talk to him about a problem I was having, it caused another argument. I asked him if he even thought I was worth it anymore or if he'd rather walk away. We broke up. We've had zero contact since. I still desperately want him back. I've spent the last several days barely eating, barely sleeping, and crying constantly. I've gotten better. I went through some self-discovery and I know where I went wrong and how to fix it. I still want him back. I think in my heart that he's the one I'm supposed to be with. He didn't delete me off of any social media like he did with the last girl he broke up with. Our photos are still up (but he's not super active with posting). When we broke up, I changed my relationship status to "single" publicly and so did he. A few days ago, I deleted my relationship status totally. A few hours later, so did he. He still had some of my dads things, and I still have some of my ex's things (nothing important, just some t-shirts, but he has some valuable stuff of my dads). That was going to be my leverage to reach out...but I'm not sure when or how. I don't want to jump the gun and reach out too quick like I did last time. I ultimately want him to reach out and want me back, but I can't wait around forever. My original plan was to wait two weeks and then text him and say that either we could talk if he wanted or I needed my dad's things back. But now I'm not so sure. I want him back...I can't even describe how much. I just don't know how he feels. And I don't know how to go about doing this the right way. I don't want to mess it up again like last time. And and ALL advice is greatly appreciated...I'm getting kind of desperate.

Who was the dumper that first time?
