Girl, that guy was a douche bag he is not worth of you trying so hard for him. I understand it had hurt your ego. It is normal, every woman would be hurt to hear that kind of thing from someone she cared about. But here's the thing: obviously he didn't love nor respect you. Seems like he was with you for your Body and not for You. And with such clothing you will only attract more douche bags. Which is only a sad cycle of need for approval and of being treated only as an object.
Don't let yourself be treated as a sex object because you are much more than that. If you bet your value only on sexuality then you will always be sad and competing. Because no matter how hot or sexy you will look there will always be someone hotter and sexier. The girl for who he left you for, will be left in a same way for another girl. Capture a man with your mind. That way he won't care about hotter girls, you will be his queen he will love you and respect you as you are. And none of the other girls will matter to him no matter how they look.
