Read the description before answering. My ex and I broke up, but I still want to have sex with him, should I?

My ex and I broke up about 2 week ago, but we were still fucking around for about a week after we did and now I called it off because I didn’t want to get my hopes up or have mixed signals about what was going on between us. After I did that he started acting like an ass with me and immediately started talking to other chicks (or so he says he is) than a a couple nights ago he went out drinking with his friends and I texted him to be safe and don’t drink and drive, than he fucking calls me up yelling at me, calling me all these names and stuff and than tells me to leave him the fuck alone, so I did, and I was hurt as shit, which from him acting and doing that shit, made me lose a lot of respect from him because I don’t understand how he could get so ugly with me for saying something like this? Like that’s all I said! But than yesterday he came to my place and apologized to me about acting the way he did, and I told him I forgave him but I don’t. I mean I still love him deeply, but after all that happened and than him trying to have sex with me after he apologized (I didn’t have sex with him though, I held my ground and didn’t put out, even though I really wanted too) and idk what to do, because I’m so fucking horny ALL the time! And I can’t see myself having sex with anyone else. What should I do, should I keep him around and just fucking around with only him? Or should I just completely try to move on? I don’t want to confuse things between us and I don’t want to get my hopes up even after what happened, I still love him! Though I don’t want to be with him, I think if I do this as long as we keep it up i might want him back again in the end. But than again I SO FUCKING HORNY!!!! Help me.
