Its alot harder on the person who didn't make the decision to separate, you have to wait until they catch up with you emotionally and they might not be ready for a long time.

Lay down some boundaries, refuse to talk in front of the children AT ALL and be prepared to cop some flack for awhile. Imagine yourself in the same position when it gets hard - he is fighting to to get his way as much as you are fighting to get yours.
