I just don't feel good enough anymore...for my fiance...

When we go out, I always see him checking out other girls ... with big ass and big tits.. we holding hands, then he lets go of my hand,an walks abit further ahead of me... I just don't feel like I'm good enough for hin... like look wise. I dont have the big boobs an big ass, an that perfect complex an nice body like these other girls he checks out when we're out.... :/ I've got very bad trust issues cause this is what every guys did to me when in a relationship... an he says he loves me,...
