Liora, first time I hear such shtusim. Oy Vey!
My husbadn bh is a wonderful person, I admire him in every way, his fine Midos I wish on everyone, and while we are both considered BH blessed with good looks, we dont look alike at all.
Try to figure out what really bothers you, and go talk to a professional or a smart rebetzin asap. Better not to tell your chosson about such thoughts, it will scare him away. resolve it with someone else asap. You need to see it differently.
MazaL Tov, Hope things work out for you!
