I read your pm, and sent you a reply based on what you had said there...but now I must reconsider. With what you have said here, it is plain that there is NO hope that she will respect you.
I stopped reading this thread right here, cause I had all the information I needed:
<< Also, about her father. He is a very nice man, and the impression I get is that he has been whipped by her mother. >>
Get OUT! Get out NOW! The girl is only going out with you because her mother approves of your relationship. Her mother sees enough of her FATHER in you to think that you would be someone they could whip into submission. If her mother thought you were your own man, she would make sure that the daughter has NOTHING TO DO WITH YOU!!!!!
Unless you want to be some pssy whipped candy ass who pees sitting down.
Be a man, and walk!
