Female led relationships discussion

Consider this mostly a place to vent. I expect folks will want more specifics, so: go ahead and ask questions. I’m not really hunting for advice; I have plenty of ideas already brewing, but that doesn’t mean they aren’t welcome.:) I’m really let down by my sub today. We share a remote, online connection with some professional elements (I work as a therapist and Mistress who helps people explore their fantasies). Still, he keeps returning to the idea that he’s learning about devotion and wants to sink deeper into it. He desires to make me happy. But… just last week I locked him up until Saturday night. He struggles past that dreaded four-day point, and I allow him some leeway because 1. he is still new at this and 2. keeping him caged usually triggers my teasing side, making those four days quite tough for him. The previous time I had him locked, two weeks ago, he pleaded to get out on day four based on accepting one of three agreed-upon punishments when I put the key away. However, the next morning he failed to appear for his punishment and didn’t show up at all for two more days because work called him in unexpectedly. I made it clear that I was disappointed he hadn’t bothered to inform me. He offered an apology. This time around, I locked him before heading out for five days. He knew our contact would be light. I told him I wanted to see how being caged worked without my constant teasing. I also gave him the go-ahead to call my girlfriend if he truly needed someone to talk things through with. He could unlock himself early as long as he accepted some penalties. On Monday night, I departed for my trip. I managed a 60-hour workweek over four days with only nine hours of sleep, sorting out a major mess (not caused by me). On Thursday, I received a message from him that genuinely pleased me: “hello just saying I. Im still caged and getting really horny and craving to swallow my cum for you to be honest that is a first!” My reply was: *“Wow. Hearing you say that really turned me on more than I expected.:)” I flew home Saturday. Naturally, I was getting tired, and as soon as I got back I checked my email then went to bed. There were no emails from him, and (my fault for being the Domme here, but hey ho) I slept right through the time I said would unlock him. Still, he didn’t reach out then either, nor since, even though I sent another note saying I was home and asking if he had lasted out his allotted time? Thanks for listening to my venting. Clearly, I’m rather annoyed, but more disappointed than that. Devotion isn’t a one-way street; it draws a response from me too. And it also shows when the reaction is completely missing. Sigh.
