Your question gave me a chuckle. I thought I would share my thought with you, it is in no way an answer to your question. :) Who were you asking? You can't be asking the females to answer because the question reads " size guys would class as obese" . If you were asking the males out here, unless I am even more abnormal than I have been led to believe, and I admit to teetering on the razor edge of sanity most days. We haven't the slightest idea of what a size 10 is. We assume it is bigger than a nine and smaller than 11 but honestly we have no clue what 10 means in woman size. We males are pretty much at our limit of comprehension with b, c and d cups.
There's an article in the UK Edition of Cosmo that you should read. This article takes a size 10 woman in her underwear and morphs her photo to look lkike a size 6 through to a 16. Then, they took these photos out and polled men and women across the UK to see which photo people thought she looked best in. I can't remember what the outcome was, but most men thought she looked better as a 12 than the smaller sizes.
If he didn't love you for who you were he wouldn't date you. Has he ever said anything? Some guys can see past the whole weight thing.some even prefer it. Sit back and enjoy the love. Plus size is 12 and up
I don't think a guy would date you for a year and a half if he thought you were obese and unattractive. A size 10 isn't fat unless you're like 4'6. At the very most you probably have nice curves and a cute shape. Not every guy wants a rail thin girl.
