Mona,
So glad that you guys had so much fun doing karaoke! I did that for the first time a couple of weeks ago and it was a blast. I can NOT sing, but I still had lots of fun.

Not sure what your H's texts were about so I can't help you there, but as far as praising/validating him why not just say something like "I just wanted to thank you for picking D up yesterday when I was in a bind. I know that you're really busy so I appreciate that you were able to make time to do that for me. Thanks again." Or something like that. Simple enough, right?
