AntoinetteNathan could not have said it more perfectly. You're body type is just as perfect as any other woman's. Women are everywhere, babe! If he were going to consider other women with "perfect bodies" it would have been an issue by now. Clearly, it isn't.
You are a beautiful, healthy woman with a loving fiance that you're proud of. Focus on how proud and enamored you are of him instead of worrying about how he feels about your body.
