I feel like my SO has the potential to be a very good leader but never seems to fully take charge.

I am following all of the rpw ways of being and this has helped a little but I am not seeing any definite changes in the way he leads. Usually when I ask for input or defer to him his response is "up to you babe" which is not really leading in my opinion. Maybe I am not being patient enough? Or maybe I am just blind to the changes?

Is there anything I can say to him to make him feel more comfortable in leading and making decisions?

I do see a slight change in his behaviour whenever I refer to him as "the boss" in a playful manner, I see a little grin on his face whenever I say this. I have also told him it's okay to put his foot down if he doesn't like something which he has done a couple of times.

Any recommendations or am I just not patient enough?
