He doesn't charge for emails, but our arrangement around emailing has taken a long time to coalesce into something that seems to work for both of us.

We came to an agreement that he would charge his per minute rate for phone calls, meaning what I pay for my session divided by the session length. At one point he said he wasn't comfortable with this arrangement, and I'm not entirely sure what he was proposing, because I told him that I wanted to pay him. Lately, we have been having fairly regular phone calls on Sunday morning, usually lasting about 10 minutes. These are usually prearranged, but there have been instances where they weren't and I emailed to ask for one. He has said that he appreciates these phone calls because they help provide continuity and connection and I appreciate them because I start to feel a lot of despair on the weekends and it helps to have contact with him. Mostly I want to pay him for the calls, but there have been a few times when I wished he would just call me because he cares and isn't getting paid for it.
