my boyfriend blocked me from social media

So right now my boyfriend and I are living in different states and we are planing to meet and travel to cancun, Mexico in week and half , but 2 days ago we had a discussion about some things I don't like from his behaviour by phone (it wasn't even a fight tbh) and he suddenly blocked me out from his social media and he is not answering the phone. He only sent me a message telling me : "thanks for ruining this trip". And then he disappeared. 
The calls go directly to voice message, can't talk to him by whatssap or Facebook, doesn't reply iMessages.... What should i do? Plane tickets, hotels and everything are ready (he paid for everything) and I don't know is he is going to cancel everything! I want to see him since we haven't for the last 5 months!!! :( help !
