Ended things because we wanted different things but may be open to it now?

I (25F) and this guy I dated from Hinge (26M) went on 3 dates.

First date: he said he was looking for something more long term, but was open to short term also. I said I wasn’t entirely sure what I wanted.

Second date: things went well and we still wanted to see each other however he ended the date saying we definitely have chemistry but he wasn’t sure if he saw us being long term. He was getting on a train so we didn’t get to talk about it and I was away for the weekend but asked to talk in person when I got back.

Third date: we talk in person. He didn’t “feel the right spark” for long term but we have chemistry, liked me as a person, enjoyed spending time together and felt attracted.

I didn’t disagree with what he had to say, that there was maybe something missing. However, with how things were at that point I knew if we were to continue in that specific moment I would still be viewing him romantically which didn’t seem fair to either of us. So we agreed to end things that day, mostly (I believe) because of my feelings/he didn’t wanna hurt me/I didn’t wanna hurt him.
We hooked up after the conversation and throughout he was very considerate about making sure I would be okay, he said he didn’t want me to regret it. The hook up itself was probably the best experience I’ve had.

We ended on very good terms and sent each other kind texts after the last date wishing each other well.

Some time has passed now and I don’t feel I see the situation through a romantic lens anymore. He was the one who initially proposed seeing each other casually, I didn’t feel I could do it at the time, but I think I can now. He treated me the best of anyone I’ve dated and handled the entire situation so maturely and kindly. I understand there are risks but I trust him to communicate with me should he accept.

Would it be okay to reach out again regarding seeing each other casually/being FWB? I’ve been told by some friends that I should just leave it as it is and move on, but other have said if he’s treated me well and think I can handle that type of situation, there’s not really harm in reaching out. Any advice?
