You like how your boyfriend turned out. Have some respect for the woman who raised him. That's what she was doing when she wasn't going to college or work. She was raising your boyfriend. The men in her family value her position so much they have always taken care of her. Guess what. They always will.

Your boyfriend can have dozens and dozens of girlfriends before he chooses his spouse. He only gets one mother.

I will guess that you are feeling pinched because after three years, you are not married or engaged. I think you know this is because the mama hasn't given her son the green light on you. I don't know how to advise you beyond to say that if you want to belong to this family, know whose family it is.
