Make sure that he's really committed to you.
I'm lebanese, and I know how lebanese men think.
I agree with some of the people who answered you.
His surrounding will find it awkward if married to a philipina.
But don't worry, I know many lebanese people who got married with philipinas, and they have kids too!!!
It depends of the guy! If he's really serious about you, go for it!

(make sure that he's not married)
