So I have been there-And I came to realize long ago that YOU and only you set the boundaries for how much you will be bossed around.
I am thinking that, since you have asked this question, you already feel uncomfortable. So here is my advice: Don't allow ANYONE to make you feel uncomfortable. Be straight up with this guy and say, "This is my life and I will live it as i please" or "I can make my own decisions!"
I'm with @vishna , that is exactly how it is in my relationship as well, we help each other and tell each other when we do something wrong but there is no bossing and if there ever was I'd want her to tell me
when he isn't letting me have a say. i dont mind someone bossing me around actually, but once it gets to the point where I'm not being heard or my opinion doesn't matter, ill get bitchy. i think it's unfair, not to mention a little sexist, to be silenced like that.
