FIB, if you were to say all those things to her, she would be hearing, blah, blah, blah. You've said them before. It wont make any difference. At some point she will realize it all, maybe. So please dont say them.
You keep saying your pain is for your children. But it is not. It is for you also. And its ok to still feel it. Your life has drastically changed. It is not the life you wanted. You will still feel sad for years to come. And it is necessary for you to feel it. If you didnt, you wouldnt be FIB.
I know it is unbearable for you to think of being away from your kids on a daily basis. I also know that you will do what you must to make their lives happy, to let them know every day that you love them, to make memories with them they will carry for a lifetime. Kids dont need to be with someone every day to feel loved and cherished.
I wish for you an end to this as it is. I wish you days where the pain is not so sharp. I wish that you find peace within yourself with the knowledge that you did everything you could to keep your family together.
