I don't know how being a control freak relates to just having a dream and wanting to make it happen. Not smoking or drinking is just a clever health choice for anybody to make.
It doesn't matter when she started singing, the point is once Mathew came in he came off as extremely controlling. There are several sources saying the same thing. It's just the vibe he gives off that makes him seem controlling/manipulative.
Extremely controlling how? Pls cite examples. Regardless of Bey's goal of fame & stardom. Any responsible black parent of a teenage daughter would be wary of boyfriends at that age. Parents arent oblivious n Beyonce has said singing was what she wanted. It wasnt forced on her. He instilled discipline in her like he should. He may have been shady on the business side of things but dont insult fatherhood cus he didnt want his daughter pregnant at 16.
How bitter he is because she chose to put her career first. She may well have been a diva as a teenager getting into the industry in that environment but it was her determination that got her where she is now.
