Re: Damn friends father.......
So sorry to hear about your friend.
Considering the facts you have stated about her, I think in her case she does not need her father's consent to get married - because it doesn't look like he will be giving it to her anytime soon anyway! Lol! Anyway, she deserves to get married and find her happiness esp' after everything she has been through. She needs a guardian, maybe ask her grandfather and two responsible witnesses to get married.
I think she should still have her dream wedding if she wants and hire security. After the London bombing, our local mosque even hired security guards so that Muslims could carry on praying!
Best of luck to her! :)
