Thanks for stopping by my thread, and for sharing about your DB coach. I looked up the DB coach web page but don't see Susie there. Do you know if she is new to the team?
I think it's great that you and your H have contact. As for email contact, I think it's OK to email him from time to time, especially if it's related to "business" type issues. And if there is opportunity to thank him or show appreciation for anything he's helped you with, go for it, especially if his love language is "Words of Appreciation".
I think it was nice that your H asked you for your opinion on the sports jersey. He must have felt comfortable enough with you to do that, and also I think it showed that he values your opinion.
My H still wears the spectacle frames I got him a few years ago. He actually tried to replace them last year but went back to the old frames shortly afterwards. I guess he didn't like the look of the new frames after all. I think he trusts my fashion taste!
