My LDR boyfriend came to visit me, and hasn’t texted since he left last night. Should I be concerned?

We’ve been dating for 2 months. He has already visited me twice. At first everything was perfect, then communication started to drop off from his side with the excuse of being busy with work. He’s opening up his own business next month. Should I move on?
