It sounds as if you have a father daughter type of relationship with him. Honestly he sounds so controlling and even toxic. If you have to stay with him forever and he doesn't change anything about how he treats you; can you be happy with that? I would guess that if you do stay together on these terms things will get worse not better because you are in a dating situation and most people try to behave extra nice during dating. I have to say you need to really look at where you are; where you are going and what you need to have from a relationship. If you are not happy now how do expect to resolve those issues? What is he looking for in a relationship? Don't know that any of this helpful cos my first instinct is to tell you to run to the nearest exit but I am trying to respect your feelings that this is the one man in the world who can meet your needs.
