Why is my boyfriend (we’re getting married in a few months) so confusing in his desires?

Right now we’re long distance. So he told me he is more and more attracted to me the skinnier I would get. I’m already underweight. Lol but I have curves so maybe he wants me to lose the boobs and ass. I’m fine with getting skinnier if it turns him on more.
the weird part is he said h can eat what I want now before we get married but that once we get married he wants me as skinny as possible (healthily).

so why doesn’t he mind if I have more weight now but it only matters once we are together and married?

I decided to lose weight and stop eating a lot. He will be so happy when he sees the results !
