I think you have the right idea Hopeful. If you can't be involved in his activities, maybe just thoughtfully ask him how it's going. One of the things my H says to me is that I'm very caught up in my own stuff and it's pretty much true. I think my H resents it.
I know you guys have the airport, and that he was supposed to get that double motorcycle seat for you, but if there are any other hobbies or activities that you enjoy doing together that might help too. And going forward, maybe dropping one or two of your weeknight activities would be of some benefit.
One of the things I started early on was an "interaction tracker" so I could track the small changes over time. I haven't kept it up lately but it did help in the beginning.
Also, have you set any small achievable goals? That might help too.
