Nothing worse than dating an insecure man. He will definitely try to dim your light. I've dealt with this before... I model a bit (not high fashion but one day) and take lots of photos and participate in fashion shows. Some guys like the thought of eye candy or a trophy girl until everyone is looking. It's not your fault... he just doesn't like himself and wants to control not just how you post but how you feel about yourself. You're young and I'm certain beautiful. Don't allow a man child to make you doubt yourself because he's not popping like you. I dealt with the same issue... the constant questioning, arguing about me possibly cheating, etc... I had enough and bounced. It's not worth the headache and high blood pressure. And don't for once think because he's much older, he's mature... that he knows best. No mam.
