If he tells you to leave if you don't like it...then that's what you should do...he seems more worried about his relationship with his father than you...he's 22 why does he care what his father says any way....nothing but heart ache here for you, you need to move on....good luck
Well, whatever you are saying is completely acceptable, and if he truly loves you and is doing this so that he is eligible to put yourself in front of his family then, try to understand this. He may not want to ruin everything that he has for you and wants to make everything in the best possible manner, he might be looking for a time when he can go ahead and ask your parents for your hand, and so he is taking time now, and if he is not telling his parents about you that doesn't mean that he is not sure about you or does not loves you, it is because he simply doesn't want to ruin this now and has plans for the future, well, for me its not like this. I would rather inform my parents about everything from the begining, so if he is not then don't be worried, look into it properly and then decide on it. And if you feel that you need to move on then you should, after all its your life and your choice.
