Mrs. H, It's okay to have these feelings. It's a way of helping you to heal a bit. Feel those feelings, own them and once they are gone, you'll feel a bit better and stronger for them.
Tomorrow is going to be a busy day for you. I hope that law guardian will be in favor or your move. I believe, from what you told us, your children are very well grounded and mature for their ages and this will help in the decision. There was no "one-sided" talk about either you or JA, that's always a good sign that neither of you is bad-mouthing the other to the children. I will keep you in my thoughts in prayers tomorrow.
I hope that you've got something planned for today. It's suppose to be a beautiful day. Get out and enjoy Mother Nature's beautiful scenery and find something to occupy your mind today. I know that the hearing tomorrow is right up front and center, but you've got to put it aside a bit today and find your center once again.
Hugs to you and the boys.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
