<human>: In January I broke it off with this guy, let's call him G, because I did not want to be intimate with him anymore. We were in this friend-with-benefits situation for about a good year. The reason I broke it off with him was mostly due to his personality.. he's a nice guy and super cute, but he's stubborn and pretty judgemental and there are many other factors that made me lose sexual attraction to him. This was just a friend-with-benefits situation and it seemed like a mutual agreement so I didn't think much of it when I broke it off, but last week he asked me if we could talk about it saying that he's been "hiding his pain" well and was pretty bummed about the breakup. We're planning on having dinner (I don't know why I can't just meet up with him but he insisted) and I was wondering what I should tell him. I don't want to tell him that I lost all sexual attraction to him due to his personality, is there something I could say to let him down easy? I was his first...so I feel like anything I tell him he would take it to heart.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: My ex-fwb wants closure. He's taking me out to dinner to discuss about our break up. What should I tell him?
