Should we run away from this Fiasco,and finally start to life we have been both dreaming for one day to happen?

I am sorry to say this but she is 23yrs.old and old enough to stand on her own two feet.There must be some nagging doubt in her mind about a serious relationship.It is up to you to convince her that you are the one for her.As far as her dad is concerned,he is worried about his daughter which is only natural and he is also worried about the relationship in general.I find in my part of the world the Polish community tend to stick together and not mix socially.Religion certainly plays a big part.I think you will have to make your own mind up,wait for her or just treat her as a friend for the time being,whatever you do,do not put pressure on her because it will backfire on you.You will never make her go against her family.
