Is he busy or is he avoiding me?

Backstory: He told me we were dating, but since that last time I saw him (we had sex).. he’s been acting weird.

We use to talk daily and I figured because he has school and work that’s probably why I haven’t heard from him. But lately he’s been leaving me on read. I’m trying to give him space but I think it’s kinda fucked up that he’s not being transparent with me.

UPDATE: If he’s ghosting me, why hasn’t he blocked me from Snapchat? That’s the only social media contact we have since we both deleted each other’s Tinder accounts.

Also he literally just started school and a new job two weeks ago. Is there really not a chance he’s just super busy?
