My exboyfriend, who is dating someone else, just kissed me. What do I do?

We were dating for 3 years and he dumped me after a lot of urging from his parents to find some one less "messed up". I had been raped a few years ago and had suppressed the memory almost completely. We went farther than we should have physically 1 night, and it brought all of those aw full memories crashing back. They were disoriented though, and for the rest of the day I couldn't discern who had done what. For 24 hours, I was so confused, I actually thought he had done it. I was later told by a therapist that that can actually be pretty common in those situations. What wasn't common is that I pulled out of it relatively quick. Any way, his parents thought I must be some sort of psychotic bimbo and forbade him from seeing me.We did any way, in secret. He would keep struggling with his parents, trying to convince them there was nothing wrong with me, but to little avail. Eventually, he said we should just take a break, but we didn't. We would have multiple "breakups" ( where we planned to wait until we were graduated) but we would always end up back together within a few days. The last one though, turned out to be real, but I didn't know it. We still flirted and everything. One day I see him sitting next to a friend of mine at lunch. I didn't think much of it until he was always sitting by her. During his last period, I peeked in his locker, and he had taken out my love post-it note. I left a note for him asking if he still wanted to get back together. I ended up having to text him, and he became very nasty. He would say, for days, through paragraphs of texts what a pathetic looser I was. He ended up dumping me for RE ALS reals at midnight. Over text.All alone. The next morning,I am not making any of this up, I had to sit through a church service about all the promises in romantic relationships and their vitality, then right after that, we went in the store to buy brunch and they were playing our song on the radio. Also in store for that day, our class was planning to go four wheeling at some cabins and spend a few nights up there as a senior party. I had to watch him and her cuddle while we watched movies, and hold on to each other while they rode. He passive aggressively bullied me. Not even a week later, we had prom. I had to leave for every slow song. By then I was in tough girl mode, so I didn't cry until I got home. During this time we had started to text. He was saying he wants to be friends. I told him, 2 times that that would be impossible, because I would have to see him with her, making the same promises he had told me, holding her the way he held me, etc. He started to bully me again, and my dad tried to help me block his number, but he would still get through. He would start off by being nice, so I would start texting him back.Any way, we hadn't had any contact since a week or two after graduation. Last night, at midnight, he texted me again asking what I was doing,and how things were going. We were able to talk a few things out, sort of. He wanted to meet up somewhere to talk face to face and give me some stuff I left at his house. We meet up and talk in his car. He admits to being a jerk, and unclear. But he still really wants to be friends. He says that it drives him crazy not to know whats happening with me all the time. I tell him how betrayed and hurt I am . He says it wouldn't have worked any way, because he is an "obedient " son. He says he is still dating her, and some how reasoned that it wasn't even a rebound. He says he didn't want to make me cry, and that's why he never made his intentions completely clear. He would also ask why I was being so mean, then he would stop and correct himself. He know admits to being the pathetic loser. He keeps trying to be comforting by hugging me and he even kissed me on the cheek. At the end though, when his parents called to ask where he was, he said he had to go soon. He asked again if we could please be friends, because he didn't want to lose me completely. I could barely even say the words,"probably not". He leaned in to hug me and he kept lingering. Then he kissed me on the cheek again, then turned my head and kissed me on the lips. It wasn't violent or anything, he just held me there for a few seconds. I yelled at him and asked why he had done that and he said,"because I'll never see you again". You don't even know how many times he's said that. What do I do with this guy? He seems genuinely confused, but I do know, that among his many traits, he is very manipulative. He even brags about it. I'm thinking of telling him that if he ever tries to talk to me again, I'll tell his girlfriend what he did...or something. I do still love him and he knows that. It's only been 2 months since the real breakup. I cannot play his games any more though, how do I get out? I'm to worn out to think for myself anymore.I know thisdes
