I want to marry from Ismaili girl

Alsalamulikom guys,

I'm an Arab guy raised in a religious tough family in Jerusalem, I got many full funded scholarships due to my exceel in college, one of them was in Pakistan, out of all countries my parents picked Pakistan for my university studies, but never mind.

While I'm here I've done my bachelor degree and master, and I lunched my business when i was in the second year and alhamdullah everything is good.

I never talked to any girl in a such way, because i believe if i bother or fool them it will be returned to me in worst way, i always respect them, if they wear a such thing i avoid looking to them, advice them, and i don't give a chance to talk about not necessary things and topics, in my life, I never experienced what my generation do regarding what they call trends and fun, at the same time many cheap girls try approach me but I give no chance, cuz we were built different.

One day everything has changed when I saw her, with no more explanation, I start see only her, I never had this feeling before, it was amazing, and again this is another exam from God.

The first thing I did is trying to reach her dad and ask for her hand, then have an engagement to get to know each other, otherwise no chance to know each other because I don't accept other ways.

During what i call investigation, I figured out that she is Ismaili, for me I accept it, I studied their belifes, faith, history, everything about them, and it became like a battle between the heart and mind, and conversation between the sword and neck.

I need to hear from you what must to do?

And did it happen before?
