That was really helpful, thanks to all of you. It is by no means that agreements, regardless of the culture , should take place beforehand. I know that his mother , for a fact, is a wonderful non-judgemental person. The house is calm where there's a lot of love. Contrary to other single qataris I met, where the mother follows every step, She leaves him on his own and wants his happiness above all. Her only condition, as it is for the whole family, is the abaya. They're very relegious. but his sisters work if they want to, that's very important for me.
