Hello naomanos;
After reading Seems Five Years Later and I Still Have an Issue With Going To Church! and from what I read of your thread and everyone's posts, I don't know your full circumstances but I do care.
I can't avoid looking at the bigger circumstance, that being your marriage. I'm sorry you folks divorced in 2016. There is a lot of mention of two churches, therefore, didn't the Ministers of these churches attempt to help you and your wife reconcile?
God is the author and defines marriage, not man or the court's decision because of a difference in where you or your wife goes to church.
Now since your wife is going to remarry, her just, has not been settled between you folks in submission to God. I'm sure there is more to this than a difference of where to attend church.
Being a man of God, priest and husband of marriage, the wife should trust where the Lord leads his servant and family to worship Him, besides serve Him.
I may be out of bounds since I don't know your whole story and for that, I'm sorry.
God bless you, naomanos, and your children.
