Guys, How to respond when he pulls away?

I’m unsure how to handle this. I met this guy who I’m really interested in, which hasn’t happened in a while because I’ve been hurt and was afraid to let anyone in. We were talking for a while and then decided to meet up. We went out three times, and I enjoyed every date (and I told him so. He said he did too). Now I sense him kind of pulling away, last time I heard from him was Monday. I tried reaching out to him the next day but heard nothing. I’m not sure if I should just pull back myself cold turkey or if I should wait until the weekend and send him a message saying “hey, haven’t heard from you. Hope all is okay” and just leave it at that and pull back. Guys, what should I do?

We have not had sex yet. He stated up front he wasn’t looking for that right away and neither was I.
