Alright so this turned into a main event.
To clarify all above comments, THERE WAS 0 EVIDENCE OF CHEATING.
She was ugly crying and blowing snot bubbles. Going from guilt, shame, ego, injured, blah blah. I'd been up for 18 hours at this point so my brain capacity was subpar, to say the least.
After her accusing me of not wanting to be married(partial truth), I told her "My life is going to keep being awesome, and I would prefer if you were in it. But having a wife that overspends constantly, lies to me, is argumentative over small stuff, and isn't living up to her potential - is not awesome. You aren't being the best version of yourself and that's what I want to see from you. My life will be awesome, with or without you; if you want to be a part of it, then I need to see you living up to your potential and being the best version of you."
She cried for a while afterwards. I gave her a kiss on the head, told her I was going to sleep and that she could lean on me while I slept if she wanted. She did.
This morning, she was very different to me. She got up, made coffee, started cleaning and had a much more feminine/submissive demeanor towards me. I guess we'll see if that was acting or real.
To those of you who've said that I haven't solidified the fundamentals, you are correct. When most guys run their MAP, the first 6 months are them just starting to get in shape. Well I'm barely 3 months into my map and I'm in very good shape... my progress and feedback have been very difficult to gauge as a result. I'm also terrible at objectively looking at myself and my progress. I can do this in spades everywhere else in life, just not for myself.
Anyways, I will continue to solidify these fundamentals and I will keep running my MAP.
I can say that my oneitis for my wife is gone. She owns no pedestal.
Thank you to everyone whose commented.
