Hi FIB - Glad to hear you're doing better. Sorry to hear the kids have to deal with you're ex's makeups and breakups.
I'm grateful that my ex has been in a steady relationship (NOT an OW - she came along about a year after we separated) that seems to be pretty drama-free. Although my kids are in their twenties, it still affects them quite a bit, so I am glad they didn't have to deal with any craziness.
My love life is more unsettled, and I generally keep my dates "off the radar" with my kids, although that is tougher now that my oldest son has come home to live with me.
Glad the financials are working out, and hope you have a marvelous 2013!
