Hm... personally, I would say that your relationship has come to an end - or at least to a critical point.
I don't think that you turn into a switch - you merely try to find compromises so you don't loose him.
It seems to me like he isn't the submissive he used to be. Maybe it was just a phase to him, a kinky kind of game that doesn't amuse him any more... I don't know him, so I can't really say.
All in all, you should overthink the whole situation. Can you imagine a "vanilla" relationship? Is he still interested in some kind of relationship?
I wish both of you the best.
