my boyfriend thinks I'm less attractive

Daniela
Today my boyfriend after telling me I should go to the gym he conceded that he thinks I'm les attractive and that my weight doesn't  bother him that much. I don't know what to think...should I take it as a intervention for loosing weight? Now I feel really insecure with him and never expected him to say that. For me he is the most attractive guy, I love him so much that there is no one else better than him to me. It hurts me a lot that he doesn't think of me that way.I am not skinny but I don't consider myself that fat. Please advice me because I don't know if I am overreacting.
