<human>: Can you condense the text into three sentences or less?

So...My ex boyfriend and I dated for a little less than a year. Things were really good. We broke up because he did not love me anymore. He was very open about it with me, but to be honest the relationship had become one sided so it wasn't really surprising. 

Regular old breakup; I was heartbroken for a little while, but not 4 months later I have moved on and am creating new romantic, sexual, and platonic relationships and I am very satisfied with my life. 
The only problem is that my ex has been very adamant that we be friends this whole time, despite my disdain at the idea. We have gotten into a few tiffs about the subject, but all in all we do share some mutual friends and I have never gone so far as to avoid him or actively dis-include him from events I know I'll be at. I've had to talk to him privately to assure him that I don't hate him because it concerns him enough that he asks my friends about it, to this day. He seems to think I'm still upset about the breakup, but I'm not; what I'm upset about is his insisting that he be involved in my life. I believe that when he decided to break up with me he decided that we wouldn't have *any* relationship - romantic or friendly. I don't feel any desire or need to be friends with him anymore, anyway. 

Anyways, he asked me out to dinner. This is a few weeks after we had a fight that was basically me asking him to stop trying to involve himself in my life, and him acknowledging that I am moving on without him and he felt happy for me. My friends are supportive and keep reminding me that I don't owe him anything, but that he's probably just lonely and doesn't have a good support system and no one to talk to about the breakup. I am completely clueless about what to do. I agreed to dinner, but I have no idea what I'm supposed to say to him or how to act.
