"The family hasn't heard any talk of you leaving or anything negative... everyone feels pretty good right now and that's great given our D is goin to to college and that's difficult... thank you for being a great parent and husband for them right now"
Tell him specific things he DID do as well as thanking him for avoiding the negatives...
