((((Jackie)))) Sorry to be just now checking in. My oldest child has been sick all week, so I've been at home too.
I'll jump on the bandwagon too!
Optimist's idea of treating your H like a guest is excellent. This stretch of time will be tough (my H let me know he was moving out about 10 -14 days before he left. Sleeping in the guest room and all that.) It stinks, but I already see signs of your strength coming through. Plan your party and plan smaller treats for yourself for the time between now and then (have you tried peppermint foot lotion yet? It's amazing!). I also think to have some nights off and let your H keep the boys is a good idea.
Great job dealing with your friend. You're right about others who haven't been in this situation not understanding. They mean well and don't want to see you hurting so much, but they just don't get it. Good of your friend to recognize this is herself!
Hang in there, Jackie. Set those goals (talking to myself here, too) and focus on yourself and the boys. Be courteous to your houseguest.
It does hurt to think of him moving out, but there really is some relief - fewer eggshells, emotional room to grieve/think/brainstorm/plan/rest.
Take care ~
