When is the time ?

I’m talking to someone and we have been snapping back and forth on Snapchat he’s currently out of the country on vacation it’s been almost a week. He’s cool kinda but now I feel like he’s just ignoring me and I really don’t understand why. The day before Yesterday he texted me “hey” and I said “hey” on Snapchat at like 1AM (we usually talk all day) but I noticed this time he ignored me alllll dayyy like a full blown 24 hour day. I was kinda upset because I was starting to like him a little. I could see if he watched my snaps like he usually does and will wait to respond but the whole day no response. I’m also assuming he’s ignoring me because one you have your snap location on and it says when you were last active so that also makes me feel ignored. We were also gonna hang out when he got back in town but now I’m unsure. Should I just blow our whole interaction off to avoid wasting my time further or just give a day or two? I know it may seem crazy to automatically want to blow it off but inconsistency is a major pet peeve of mine. From my perspective a nice lil snap saying something would have sufficed instead of ignoring and STILL using Snapchat. Don’t crucify me in the comments I’m also going by what other people would tell me too if you can bring some light to help me not worry about this it would be nice.
