I’m confused ...

So basically, I reconnected with my ex and we hung out and it was amazing. We both talked all night how good it was to see each other that night and kept texting good morning and goodnight and now a week later... we talk but not like that? Like we just snap each other pics but he leaves me left on read eventually. Like we both post hmu and he’s always the first to view my story and just like I don’t text him cause I don’t wanna annoy him but I don’t know if he’s secretly wanting me to text him or what’s going on? Ugh...
