Mark, you blew her away with giving her the money. She just got home from being out of town, so you know she was 'ready' to fight. Wants 'reasons' to leave you, reasons to say "See what a jerk he is, everyone?". You totally did all the right things!!! She is spewing that's for sure, but I think she is also measuring you up, for what fight she might have with you, regarding money or even the kids. I love that you held your tongue while she accused you of having an affair. Sorry about that text Joking!
You have your plan, you are ready. What she isn't ready for is your plans! Way to go.
