I’m worried my fiance will leave me for my pretty bsf, help?

My best friend is a lot prettier than me, and just cooler-I know it’s weird but I’m so worried my fiance is going to leave me for her..

like I know he loves me but she’s a lot cooler than me and I am just worried. They both like the same stuff and are a lot alike more alike than him and me.
