Of course Haya consented herself i don't believe she was forced into the marriage.
What i was trying to put across is that Haya may have married her ex-husband for other than romantic reasons that most Western people would enter a marriage.
She was getting to an age where most women of her age had been married. I assume there was no acceptable love in her life to be a potential husband and here was a no doubt charming man of the right faith who could also help the people of her country and probably presented a future that was both useful and filled with things she would like.
My take on it is that Haya did not marry with her heart but with her head. He was a proper husband for a Jordanian Princess. Marrying him would give her a family and the kind of life she thought she liked. Unfortunately things turned out not as rosy as they were presented to her and again i doubt Abdullah had any clue of that.
But I'm not really believing Haya was head over heels in love with her ex-husband. I believe she married a man she thought was a good candidate but who turned out to be much less pleasant than presented before the marriage.
