I understand why you would feel that way. But I'm guessing you were with your fiance before you lost all that weight? If he loved you when you were overweight, he is going to love you with smaller breasts. I know how you feel because when I lost 35 lbs last year my bra size went down almost 2 cup sizes. I like having a smaller waist but not smaller boobs
You are still the person you were before you lost that weight. Which I meant to say CONGRATULATIONS! That is amazing. 70 lbs! Even if you're breasts are smaller you are healthier for having lost that weight - both physically and mentally.
And plus, all those women you see on tv and in magazines - that's not even what they look like. All of that is fake and you should be proud to be real - no matter how you look. At least it's you!
