First thing....cheer up!!! Don't look at it as you all spending time apart, look at it as time for you to have to think things through. I'm sure he will miss you. Men have a weird way of showing their feelings. I think it is good for you to not initiate contact. Let him contact you. You might be surprised.
Hang in there. I'm sure not feeling well doesn't make it any easier. Don't let yourself get run down from depression or anything this week. Try to keep your spirits up and do something fun for yourself.
