I'm sorry that you feel that way. I was going through the same thing with my last relationship. Get out now before it destroys you completely. With my last relationship, i gained 30 pounds, my hair fell out, hell my period even became completely irregular(Ik TMI). Im telling you this because it isnt worth it. You are a beautiful person and no one should make you feel unhappy or insecure. Just remember the person you were before you met him and try to get that person back ASAP! It will be hard to leave him but in the end you will be much happier. I wish the best for you and good luck! God bless you
