I recently read a post on here about a male dom who just seemed bitter and burned out, disappointed with himself, dissappointed with his submissive, and disappointed with life in general.
I can't remember whose blog it was now, but I did honestly feel bad for him, whoever it was. Sounds like he was going through some rough things, and relationship wise, things didn't work out for him, and I know how sad and disappointing that can be.
I will say that, relationships, even D/s ones, can sometimes be more complicated than they want them to be. I know my own limits that I could never be a 24/7 slave. And I'm being honest with myself, and whoever my potential partner would be, when I say that. Because I have my own job, my own hobbies, friends, interests, and obligations, and I simply would not be able to commit to that. Maybe some would say that makes me a "Fake Submissive." But I would think that even a 24/7 slave would want to have boundaries, or their own interests, their own part of themselves that is theirs, and their own time for themselves.
And I think it is not unreasonable for a dominant one to want to grant that. I can not speak of the relationship I read about in the blog I mentioned. I know nothing about it, or what really happened.
But I would expect that even if I was a dominant, I would still want my own space, time to do my own thing, and wouldn't be prepared to just order someone around every waking second of the day. It would be hard to keep up that facade all the time, to never feel vulnerable. But I can't speak to that either, because I'm not a dominant. I just think that every relationship is different, it's not always as simple as "Just worship me 24/7" and everyone (even dominants) need to sacrifice something to make it work as a couple.
