What just happened?!

Hey ladies and gents, what do you even do when a guys you’ve been dating for 6 months just drops off our of no where. The last conversation we had was on Saturday night to where he just never responded back and now it’s been four days I haven’t heard a word. Everything seemed fine idk what happened.

Any advice would help. Should I reach out or just not even bother at this point? Thank you!

UPDATE!!!

So I decided to reach out and send him a simple text,

“Hey there, haven’t heard from you in a few days. Just wanted to make sure you’re okay.”

Haven’t heard from him back yet. But one of our mutual friends, mostly mine just informed me that he had posted on his Instagram story about an hour ago, which is around the time I sent the text…guess what I can’t see his stories. He blocked me from viewing them, but still has me on his Instagram…ugh. I guess I got my answer…
