Yes by all means call him and call him some more. Go to his house, go to his work. Just remember, you don't have to tip the Sheriff when he gives you the restraining order.
No, just go do something, enjoy your day and quit thinking/wondering. But when he finally does call, play it cool and ask one thing...ANYTHING I NEED TO KNOW??...he may ask what you mean, playing it dumb, but just ask it again. He'll confess to something or simply get the idea not calling isn't cool.
No id ask him if he has been seen any one outbreak than u
