Am i weird to think about exclusivity?

Hello. 30f. 3 months ago i met a guy through a dating app and 2 weeks later i decided that no longer want to do this online dating thing. So i deleted the app. However, i continued to see this person. Now that we know each other a bit I can’t help but wonder if he’s seeing other people. Tbh, I am starting to really like him. But also, it bothers me to think that he doesn’t seem to care if I see other people. I don’t want to ask him to be exclusive just cause I am feeling this way. But now if I continue seeing him i might get hurt. I don’t want to go down this road again. Not sure what to do. Any advice?
