My ex husband left me three years ago for a prettier woman. She is taller and thinner than me. I am by all?

means not heavy at all, but she has the height on her side. She has big blue eyes and i have green. I still can't stop comparing myself. It doesn't help either that I haven't been on one date since. I am very outgoing and friendly , but I still can't get a date. I want to get out of this funk, so I can move on. Any suggestions?
