I have a set day and time now, but I first started seeing him, it was usually set day but different times, and it was only every other week. I think he remembers because once he forgot to put me in his calendar but texted me to see what time we agreed on, so he knew I was coming that day. But that was at the beginning, now it almost never changes. I think he also has my name in his calendar every week so he doesn't give it to anyone else.
