Not muchto offer LSG except to hang in there. Your kids know how hard you are trying and the money she spends on them will make no difference in the long run. You are a GREAT dad to your kids and they appreciate it more than you know. Kids are so perceptive that it is unbelievable. My kids know so much more than I give them credit for and yours do too. Just keep doing the best that you can. They will see it and love you for it no matter what.
