Quite honestly if you read up on the other situations here, most of the ones that are turning around involve a husband that did move out. And actually without him there even though that is SO difficult to have him away, at least you don't be walking on eggshells. I remember when my H moved out of our house, 5 days after the bomb. I know how you are feeling. I'm so sorry. You need to cry. Then get some extra sleep tonight. Call up a friend tomorrow and talk. Or get out of the house if you can. These are the hardest days to get through but you will find with time, they do get easier. I promise.
Most of us really marry only once. First love endures, even unto our dying day. And we never really divorce.
