Hello and welcome
Maybe emailing, etc. isn't his communication style? My secondary (Possibility) lives ten minutes from me but due to schedules being what they are we rarely get to see each other more than a couple of hours a week. Getting him to communicate via computer or phone is so totally nearly impossible! If I want any meaningful conversation I have to talk to him in person. He does let me know he got my emails but doesn't generally impart meaningful information that way.
Stating your needs is the only way you can know for sure that they know what you need so good job on that
