I agree with Painter about the previous attempt to validate her feelings. When you are sending typed messages, the tone could be negatively received. I believe you mean well, but at times, it comes across as though you are mocking her. So, yes, better that you took that sentence out.
The only other suggestion might be to change "getting 5 boys ready" to just "getting the boys ready". She knows how many kids you have, and previously, she had the full time job of getting them ready for activities. From what I remember about your early threads, you left those type of thing to her, and you brought home the paycheck.
I agree that you should have taken her off your phone plan.
You are doing a wonderful job with your housefull of little men.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
