Being a body builders wife.

Hi, I'm currently engaged to a body builder and he makes me the happiest woman on earth for the most part. He takes care of me in any way he can. But being his fiancé I feel pressured to start working out as well. I'm 5'2 148lbs, I don't believe I am fat, I am considered over weight for my height. Of course just like most women I'm self conscious about certain aspect of my body. But it's gotten worse since we got together.  I've asked him for help to Lose weight but every time he tells me I can't eat a certain thing I Alianate myself so I can cry. Yes I asked for the help but only because I felt like he would like me better if I was skinnier. He tells me I'm beautiful the way I am, but has also stated multiple times his dream is for us to be this fit couple together. It's hard feeling like you're not good enough every single day. Please give me advice. Tough love welcomed.
