How much time does he have when he's off work? Maybe you can just talk to him and set up a date for one on one time. Even though you both have outside activities to keep you busy and your own hobbies, you still need to take time to reconnect with each other on occassion. Have you talked to him about how you feel? Maybe he's not even aware of what you need. He may be quite happy to take a couple hours to spend with just you, and maybe he even wants it, too.
