Liora, Mazal Tov on your engagement ;)! When a person’s bashert is decided it is a zivug of their neshamos. A person’s zivug is NOT decided based on looks. It seems that although so many people have mentioned that looking alike is not a pre-requisite to a happy marriage, you are still bothered by the fact that your chosson doesn’t look like you. I’m sure that when you get married you will forget about this narishkeit and realize that looking like your husband is not required for one to be happily married.
Also, just out of curiosity- is it your personal opinion that you don’t look like your chosson or did people tell you that? Perhaps if I saw a pic of you and your chosson I would think you have similar features.
Really- don’t be worried about this- always remember H-SHEM YAAZOR!!
