I am 19 years old and have been dating someone for 2 years now. We love each other very much but there is one thing I don’t like about him, which disturbs me a lot. He thinks I am fat, which is not right. I agree I don’t have a flat tummy, which is what he wants, but I am not fat. We have heated arguments about this. He also thinks crop tops don’t suit me. I have started dieting and going to the gym, working hard on my body even though my own parents don’t think it necessary. He still taunts me when he sees a girl with a perfect body, and this hurts me a lot. He should be with me and support me, but taunts me instead. I have spoken to him, but it doesn't seem to work. Please help. I can’t take more taunts.
