I am so happy for you being able to coach BOTH boys this year! That's great! And, the text exchange above sounds positive too! Look at you!!!
I also wanted to chime in from a woman's perspective... well, more a wife's perspective and say that seeing your H getting involved with children, having fun, making them laugh, helping them realize their potential, encouraging them...
Frankly, there's nothing sexier. NOTHING.
Take that and run, my friend. I know you're doing it for all the right reasons, for your boys so that's really great but remember, she's noticing (as are all the other moms, trust me).
Enjoy it, make it fun and look good because you're on.
