How do you get your ex back if you really want him back?

About 2-3 weeks ago, my boyfriend of a year broke up with me. It's a long complex story but I'll spare you the details but in a nutshell: His mother was/is a control freak and is never satisfied with anything. She was making assumptions that weren't true which just led to controversy between the families (my family and his family.) She pulls this stunt about every 4 months and I figured it would blow over like it usually does. Well, it didn't. It had reached it's limit and became too much for my boyfriend to handle. He broke up with me very unexpectedly..and said that he needed to get his life back in order. That he needed to get his friends back (that he severed ties with when and I began dating) and we both had a lot of growing up to do. He said he wished to remain "really good friends" and down the line, he'd love to get back with me again. He was very upset and just said that it got out of our control. I knew weeks before that we were having problems based on how the relationship started out (i.e. we spent too much time together, we both got to be jealous and possessive to an extent, we rushed into many things too soon, etc.) but I never thought it would lead to this. I knew what went wrong and I knew what I needed to do to fix it..but that opportunity wasn't offered.

Needless to say, I was devastated. Here we were, 20 days before our one-year anniversary, and everything had fallen apart. The week after our breakup, both my mother and his family were to go on a vacation that we had planned for the past year and because the families weren't getting along - we didn't go. After about a week or so, my mother felt that things needed to be mended between her and his mother (just because she didn't want any hard feelings.) They talked..and everything's been peachy between them ever since. Last Friday, I went to get my stuff from his house (I had basically moved in) and since we had agreed to be "good friends" - we decided to hang out for a few hours. We were getting along good..laughing, cracking jokes, etc..and then things turned very sexual. The sexual tension was so thick you cut it with a knife. He was all over me..and I was trying to resist..but after a few kisses, I gave in. We didn't have sex but we came pretty close. I knew that if he and I had sex, it would tear me to pieces and makes things that much harder. Not to mention, I would be out of "the game," so to speak. So we basically did everything but that. I told him I didn't want to be 'friends with benefits' and he agreed. - because that's what one of our main problems was in the first place: we were never friends first, we jumped right into being boyfriend/girlfriend. Then yesterday, he and I hung out again - and it was pretty much the same. This time, he was trying a bit harder to not turn it into a sexual thing..but that soon went out the window and we came very close again. This time, he was begging me to give in..but I refused to. He told me that he's single and he doesn't feel guilty about any of this. That we could keep what we were doing just between us..and it would be no one's business but our own. But that if it got to be too much for me..or him..we could always say no and stop it then and there. I told him again that I didn't want to become friends with benefits because that would just lead us to more problems. He said that his best friend is worried that he'll come back to me due to the sex. I asked him why, and he said.."He knows me too well." He then tried to come up with something to tell his best friend about what we had done (his friend knew he and I hung out that day). So last night, when he dropped me off..we agreed that we were going to work on being "just friends" without trying to have sex with each other every 5 minutes. He also agreed and said that, if we don't become "just friends" - that we'll never be able to get back together as boyfriend/girlfriend (which is what I really want.) It's just so hard..The spark is so strong..I guess I'm afraid that he'll never come back around and want to be boyfriend and girlfriend again.
