She praises her husband too much in this Letter. She wants him around as an ATM so she sweetens him up and absolves from a lot of questionable behavior by refusing to ask questions.
She shouldnt write to the mistress, she needs to write to her husband.
Shes stupid enough to repeat the negative shyt her husband said when he was found out. Will she also believe all the negative shyt he told his mistressand friends about her?
Finally, too much emphasis on herself, not enough on repairing the relationahip with the kids. The kids are barely mentioned at all except as ATMs for 'her' money.
I think she was stay at home by choice, not by force. Her husband was out on the prowl because she wasn't doing shyt at home except spend his money while the kids ate bologna or mcdonalds.
Husband should seek full child custody, no matter how much money it takes.
