How am i supposed to be confident about how i look after all this?

Oh sweetie that guy is just bitter because you broke up with him. I`m sure you are very beautiful and if others don`t think so, screw them. The problem with people these days is that they base beauty on unrealistic celeb "beauty" and plastic surgery people. Thats not beautiful in my opinion at all! The only real beauty is natural. One day you will find someone who honestly finds you the most beautiful girl in the world. Look at it this way hun, we all have imprefections, but these imperfections is what makes us all unique and in reality, beautiful. You shouldn`t take what an ex says to heart, often times they feel hurt after breaking up and will say things to bring you down, it might be because they are themselves insecure and want you to feel that way as well so that you stay with them outta pity. Whatever his reasons are for saying this, its not right and can be a confidence destroyer. Don`t listen to him, get out there and meet a new more apprecative man. Just know Mr. Right is out there, he might be already in your mist, you might meet him tomorrow, two weeks from now, or in five years from now. Just know you will meet him, he`s coming to you as fast as he can. Just remember you are beautiful in your own way. Good luck beautiful! :) keep your pretty chin up!
