Dominant?

Yesterday one of my very best friends decided to sit and have a talk with me and my boyfriend (who is also HIS best friend). He said that I am too dominant, he said that I make Fou (bf) lose all the time he needs for his thesis for his masters. He said that I am making him too dependent on me, that I dont give him enough care. He said that it's my fault that this relationship "look" like a good one and that we are two separate people not one unit.
Now, we have to think about this for a second.
I'm dominant? Why am I dominant? Just because I don't act like the all-weak-always-sitting-next-to-her-boyfriend kind of girl?
Is is because I can sit wherever I want and say wherever I want and disagree with him? Because I dont just shut up and not say my opinion about anything?
Maybe,
The truth is, thought, I dont want to be one unit. I am Sara, and I love being Sara. I dont want to be anyone else or merge with anyone else- we are two different people who love each other. This does make us have a certain bouding, yes, but it does not make us one unit; simple, because we have two different sets of brain cells!
I was so angry yesterday...I didnt feel well about the performance and I was almost not going to get up on stage to begin with. Gogo just kept trying to make me feel less nervous. Obviously, that worked. It was a great performance and everyone said I did great.
Today I am a lot less angry about it. I will not say all what I have for the friend because I know why he said that- he's my friend since 9th grade and I know how sometimes his own insecurities just flood on others. At least, though, I know I am not what he claimed me. I am not just dominant for the heck of it and I am not a fan of having a submissive man and all that political shit.
