Your emotions have to run their course. If you keep your mind occupied, it helps. You should take the time to learn something new and do something you used to do a lot that you don't do anymore because you didn't have time. Don't talk to him, just keep your mind busy. If you feel like crying, then cry. Tell a friend and tell them you're a mess and that you need to get out of the house and your mind off things and just stay busy.
