First off... I'm really sorry you had to go through that, though I'm the other hand I'm glad you're rid of him. While you may have liked or even loved him, he didn't love you in return and for your sake I'm glad you didn't end up in that relationship for any longer than you were.
Second, people try to degrade others to justify treating them poorly "she's just good for sex no one else could REALLY love her so I'm no different than anyone else." He said that to hurt you for the sake of hurting you. Not a word of it is true. The very fact that you're dedicated to and are working towards your dream goes to show you have determination, a sense of drive, and dedication. Nothing that happened was your fault as far as I can tell. And you've proven simply in the fact that you acknowledge you were more distant that you are a sincere person, to be loved and treasured. If any tell you otherwise... well they're lying to you. You're special and hopefully there will always be people who see that in you. ☺

Honey, you're a human being. No human being is only good for sex. You have a brain, you can think and do things. You are good for whatever you want to be good for.
Look, at the end of the day, he cheated. Everyone knows cheaters are the scum of the earth right down there with pedophiles and people who hit old ladies. He's a bad person, anyway. Why would you take the opinion of someone like that, seriously?
Just realise that you made a mistake by being with such an asshole. You're free now to focus on you and to find out all the wonderful things you're good at, most definitely more than sex.
