Chandra,
I'm sorry you are going through this alone!! I agree with everyone, you should have all his stuff as close to the front door (if not on the porch) so his time in your home will be as quick and simple as possible.
There really is no way to get him off your mind unless you occupy your time with something that won't remind you of him. My escape from my A or any other situation is running. I have found that you can't consentrate on anyone while running. You're to focused on your breathing and strides to be bothered by anything. I've found that by the time I get home, I'm to pooped to sulk or be angry. Thats just a suggestion. If you can't run, walking is always a good alternative. When I first started running I couldn't run more than 100 yards without stopping. Now I'm up to 4-6 miles without stopping. You'll be in my thoughts and prayers tonight!!!
