For those of you in the middle of this who are fearful or hesitant. Stop a moment and visualize your life without him in your home. Picture the peace. Picture the quiet. Picture yourself locking the door with him on the outside forever. Picture yourself on the sofa watching what you want, quietly reading a book, or just 'being' without that sick feeling of walking on eggshells or dreading the sound of that key in the lock. Picture your children eating peacefully at the dinner table, watching telly, doing homework or just sleeping without hearing raised voices, feeling that tension between the two of you (don't think the kids don't feel it, because they do), or being shouted at.
Now close your eyes and really feel it.
Now open your eyes, make that plan, and carry it out. Things won't be perfect, they never are. But they will be better than where you are now.
