I'm very glad you had a good father's day, LSG. I'm also glad that your kids realize the great father they have.
You sound so much better recently. That makes things easier on you to do what you need to do. Easier on the kids, too. You can be more relaxed around them and the STBXW and not let things bother you and can concentrate on your relationship with them.
Keep up the good work. Keep up the job search. Something great can come out of this, I know it.
