A marriage ending and having to cope with still living in the same family home albeit at different times must be extremely difficult.
I understand through finances people must do this but it must be hard, especially if one party was not wishing the marriage to end. I would look at every possible option of trying to have different living spaces whereby you can heal.
I don't think many could cope with it.
I asked because a marriage ending for some means the beggining of a new life and that often is hard due to concience, guilt and still feeling watched and not entirely regaining their single life again.
On the other hand if the marriage was made so bad by one party wanting the union to end so as the other partner felt they were pushed into divorce, the pain of remaining with somone who you still love is heartbreaking.
You both may have come to this decision together but there is usually one that initiated it, not the divorce but the devaluing of the union, leading to divorce. There will be one who deserves more kindness and the other should be more accomodating but that doesn't happen often, thats why it's best to both have your own homes.
You are worried about losing the children is that because you want to leave and the children will stay will him, due to schools etc, expensive housing ?
Can he not move out permanantly and he have them visit.
