In this situation I say there is nothing to worry about yet , there's always a reason , and seeing as you guys don’t know most about each other I don’t see if hes turned off about you , maybe it could be you haven't said hey or started the convo , and he doesn’t know if he should start the convo or not , he may be shy or hes just plain busy , see if hesseen the message and if he doesn’t reply he might be a guy with few words and doesn’t respond to statements only questions , but don’t worry im sure he is not ignoring you , and just don’t be too obsessive over it .
