Paula there are alot of social issues when dealing with men of other cultures.  

Is he christian or Muslim lebenese?

How religious is he?

what is his family like? (as they are a reflection of himself in many ways)

 What does he expect in male/female roles in a relationship?

What are the beliefs of people in his country? Child custody, divorce, domestic violence, talking with other men?

Is he jealous?(Alot of arab men are not very happy with their wives talking to men although many do not show it when they are trying to catch you!)

My advice would be to take your time about having children with him. Get to know him and his family first. And let them get to know and accept you! And have an exit plan should you marry him! 

I helped to arrange a marriage for an english girl. And because the mother accepted who she was and her way of life.. they are now very very happy in her situation. And has just arrived safely back from a trip to his home country. It has taken alot of understanding and TIME from both sides but it can be done.
