How do I respond to this?

This text came from a guy I had talked to for a little while. He was actually a really nice person and I did think highly of him. We had a lot in common and talked on the phone for hours. He took me on one date and then I ended things because I ended up doing it with another guy who I had been friends with for years. Also, this was the first time I had sex in 5 years so I broke my celibacy. I didn’t expect for that to happen but my first thought was that I shouldn’t lead this man on. So I told him I could be friends with him but that it was getting serious with somebody else. In all honesty I don't know what is going on with me and the other guy but I do know that he and I are progressing towards a relationship but none of us actually wanted to jump into one just because we had sex. Yet, I like him a lot and he has been my friend for years so I believe that it could work out. I genuinely didn’t mean any harm towards this guy I just hadn’t known him long enough or got serious enough to continue to try to talk because I thought it might just be a waste of time. I hoped I hadn’t hurt his feelings and wondered if he was okay. He seemed okay and like he understood. We still had friendly conversations but I don’t reach out to him anymore and I keep things as strict friends. The guy I deal with knows the situation and told me he stopped talking to other girls as well and that if anybody asked he told them he had a girlfriend, he also had told his family about me and met my family. I don’t mind still being friends. I just think with the way he worded the question in the text gave me an impression that he might still be interested. And I don't know what to say that I haven’t already told him that won’t hurt his feelings because it isn’t about him at all. I just genuinely have feelings for my friend and want to see where it goes without jeopardizing anything. So I wouldn’t personally mind hanging out if I didn’t think this man had other intentions
