Crush on older guy

FYI I don’t think I have a crush on this guy, I did, but now I don’t I just need it to be relevant to get answers.

Back in the summer I met this guy he was 28 and I was 18 and we ended up hooking up. Please leave the judgement at the door I have not come here for that, I know what you must think but honestly he did not look his age and he was extremely attractive, I would not have but him any older that 25. we met via Grindr (both gay) and hooked up about 3 times. The times that we spent together were very good, during sex he was extremely respectful and kind but also we spent a lot of time talking and chilling before and after the sex act occurred. I am ashamed to say I did get feels for him and I won’t say that he did too, but he did keep saying how he liked me and that I was nice. Anyway after we met a couple of times, he told me not to get attached and then thing ended when he went back to the navy.

Now in December he is back and he wants to meet up again for obvious reasons and I am so torn. Part of me wants to go, maybe for that thrill with him again, but part of me thinks its a bad idea because I will just get caught up in the feels again. I want to say no to him, but then I don’t want him to go and find someone else to do things with - does this make sense?
