maybe i should forget about him and move on and think about guys that will treat me right and not just look at girls like sex objects?
Of course you should, but don't forget that people will treat you how you treat yourself. By the tone of your post you describe yourself as inadequate. That is how people will see you and treat you, whether they intend to or not.
Another thing: recognize wishing as the bad habit it is. Nothing has caused me more grief than wishing everything was different. It's nothing more than a momentary ego boost that leaves you with even more loathing for who you really are. Don't let yourself indulge in those incessant fantasies. They are only exercises in self-hatred.
Instead, identify areas of your life you can improve and pick one and work on it. Do something concrete. Develop some good habits. This site is full of ways to do this.
I find working on physical fitness first helps inspire one to change other areas. It's not about making a physical transformation as much as simply respecting and honoring your body, as a habit. It is hard to dislike yourself when you do things to love yourself regularly.
