I work in a school. I have read your recent posts and I wanted to say that it might be advisable for you to call your daughters' school(s) and speak to either the Dean, Guidance counselor, or Assistant Principal about your daughters. You don't have to go into extreme detail, but just let them know that the girls are having a hard time with some family issues at home, and this will give them a heads up. They may need some extra support from school officials and teachers, especially your oldest. I have seen it many times; it helps if the people in charge of your kids at school are somewhat aware that things at home are a little crazy right now.
Most of us really marry only once. First love endures, even unto our dying day. And we never really divorce.
