What would you do ?

I told my boyfriend how I felt about him liking other girls pictures and all he said was "relax I love you how you are" but I feel that is a lie. When we like a picture on Instagram its because we like what we see. Most of the pictures he likes are of girls that are lighter then me in weight and that are hardly wearing any clothes. It hurts my feelings because it makes me feel like I'm not good enough. It also puts this pressure on me to diet 10x harder and change my dressing style. I hate feeling this way.
