What should I do?

So just this week I reconnected w someone who I used to talk a few months ago. We just faded and stopped talking. He says he likes me, likes talking to me, says he wants to kiss me, indicates he’s interested etc. and I feel the same but I’m thinking he’s really not as interested. He goes all day without talking to me and last night I texted him and said “You can just delete my number if you want” and he says he just works all day and stuff. And I thought “okay understandable”. But than today he has yet to text me, left me on open from last night, but yet views my Snapchat stories. Idk how to go about talking to him bc it just really seems to me like he’s not interested like he was saying. I’m thinking of just leaving it alone and waiting for him to reach out to me but idk what to do. I just don’t get it.
