You have a good understanding of what to do based on what I read in your posts. The emotional roller coaster is normal, and the reactions of your W seem textbook. Keep trying to avoid reading into her reactions as you make changes. The changes are for you and if you feel good and confident, then any accusation she makes is irrelevant. And you are correct. This is all easier said than done. But so is bench pressing 250 lbs at first. It takes time, daily practice, some mistakes that you learn from, and persistence .
Only this will make the changes permanent, and only then you will be the person only a fool would leave, and then you will be strong enough regardless of her choice to move forward .
For now be the best father possible, hang in there and stay in the moment.
In answer to your question, IMHO, send flowers only from your d. Gifts from us at this time are not recommend .
