Dating???

So I met a guy and we been talking for two weeks straight! .. after the last text I replied and he never responded back, so I texed him the next day asking if he was okay!? Called him and he didn't answer so I got worried and msg his sister to ask her if she can let me know how her brother is? A week later he sends me a msg saying he had an emergency and left to mexico everything happened so fast and he left his phone at home without telling me, his really mad at me because I got in contact with his sister and now I'm on her bad side! And he doesn't know what he wants so he needs time to think!!..what do you girls think of this??..what should I do!?
