Is it cheating to have a casual lunch with an ex-hookup?

Anonymous
A few weeks before I met my boyfriend, I hooked up with someone else. We never had sex, though, it was never serious. I eventually thought he was no longer interested and eventually met my current boyfriend, who is the love of my life. It's been several months, and the guy who I had previously hooked up with talked to me again. He knows I have a boyfriend because I told him all about my boyfriend, and made it clear that I was unavailable, but he told me that the reason we stopped talking was because he saw me with my boyfriend and figured I was unavailable (I met my boyfriend shortly after I hooked up with him). He wants to get lunch with me at our college, which is fine, because nothing physical would happen and he's a nice person as a friend, but I really don't want it to be misread by any of my boyfriend's friends, who might see us. This guy is nice but since I've been with my boyfriend I can't possibly see myself hooking up with someone else, it just seems so wrong and disgusting. Is it bad to have lunch though? My boyfriend is still friends with his exes, and this guy isn't really an ex at all, I don't have any feelings for him whatsoever, I just think he would make a good friend, and when it comes down to it, I'M the one who makes the decision between friends and something more, and I would never be something more and I have a feeling he wouldn't want to be either, because he's interested in other girls. But is this wrong?
