Does too much care or concern annoys you? I feel it so annoying and I am guilty though.?

I am living with my BF's apartment with his mother for 2 months now. His mother cares too much for me and her son. For ex. from cooking, washing , cleaning and almost everything. She does everything everyday and I am also helping her in most of the time but she always says that I must not do this and do that. She likes to do everything but I feel like she doesn't trust me or her son for doing something. She tires herself for us but then she keeps on helping us even the simple housechores. She oftentimes complains that his son knows nothing so she must help him. I lost my confidence because she doesn't give me/us the resposibilities. I used to be an independent from my family. Now, one of the disadvantages of this is that her son seems very dependent to her though they often argue for something because her son doesn't like to be treated like a kid. I even feel the same. We are like kids in her eyes now. I sometimes regret of being here but I can't leave my BF just because of her mother. What I want is to learn to be ourselves because we are planning to marry soon and we want to prove that we can stand our own and this time must be the right time to test ourselves. It hurts me when I observe that my BF is quite dependent to her. I am afraid this will lead him into not being a responsible husband. But her mother is a great mother though, just her overcare or overconcern annoys me. She spoils her son. They are not healthy I think becasue we are adult and we can take care ourselves in all means.Phew! Anyway, any ideas or enlightenments out there bec. I just want to express my feelings inside me.I admit, I am such a ***** for talking bad things to an old woman who is doing everything to us. Thanks a lot. Sorry for being long!
