I am much heavier than I appear

I am a female around 5’7. My boyfriend thinks I am around 130 lbs maybe because I have wide shoulders and a wide body frame? But I am actually around 165/170 lbs. I feel so embarrassed to tell him how much I actually weigh, especially when he guessed I was around 132 by judging my body size. I feel really embarrassed and less womanly. 😔 he weighs less than me

And yes I know I will start working to lose weight. Just feels bad
