Should i confess my feelings for him

So i have been having sex with this guy i met on vacation, after we went home we met up twice. I think i like him and I would like to get to know him better.

At the beginning he said that he isn’t necessarily looking for something serious right now, but he did say that we get along well.

Should I be honest and tell him that I would like to get to know him better, or am I not respecting his boundaries if I do that? (Bc he did say that he isnt looking for sometings serious)

Thank you for reading :)
