Help me!!!

I'm in a heavy stitch!😭 I've been in relationships left to right one after another and I finally put the foot down and stopped getting hurt by others so I just recently started seeing this guy, he's smart we hang out, have sex, talk, he's sweet and caring not all that attractive but I don't care for that. And I like him. After that he told me he was sick 😦. Problem is someone I had spoke to before him ( just talking) had came back in the picture saying he misses me and he wants what we had back even if we are just friends and not talk like that,mind you the guy is cute funny sweet outgoing smart and optimistic and we stopped talking because he had no time to. I really like him to. This might look bad but I guess there is some guilt in me if I stop talking to the guy that told me is sick. But I also want to have fun and not be bored with the other guy. Uggg I'm not in a relationship with either of them and I don't want to be the bad person I like both of them what should I do. Be nice about it gals!
