Getting Mail in Jordan

My question is, how do you receive mail in Jordan?  I have sent two pieces of mail to my future husband in Petra over a month ago and he has still not received them.  When we get married and I move to Jordan, I need to be assured that I can receive mail from the U.S.  Is it better to get a Post Office box in Amman?

Thanks SherriO, should I get a post office box at the Amman Post Office?

postal service is avilable every where , there is a post mail office in petra , all you have to do is go register your name , address and pay few dollars only , they give you a key and you go to the office check your mail box whenever you want .
