He blocked me!

What should I do when a man I like blocked me on WhatsApp? He blocked me the next day we found out that I am not pregnant. Do you think this’s the issue? I don’t really get this ‘cuz we were both super chill both before and after this situation...

FYI, we have been seeing each other for the past two months, and it’s not like he is young and immature. Well that’s what I thought. He’s 28yo
