wow. I'm sorry.. this is just not okay! if he treats you like this now, will it be okay once you have kids and your body is even more different!?
You are 23.... not 43, not 63... 23... probably around the same age as the girl doing the dance.. he has absolutely NO RIGHT to treat you like that.
has this happened before? Does he do this regularly?
Sorry, but personally if I was with someone who made me feel like that as a young, vibrant, 23 year old.. who hasn't even had kids yet... I would be really really questioning whether that's something i'd be willing to risk feeling like once kids came along... I'd leave honestly. That's just BS.
