His reason for breaking up with you is one of the oldest in the world. I'm sorry, but it wasn't about love for him. He was just trying to manipulate you into giving him sexual satisfaction, and your feelings didn't matter at all. You could have been any girl. That's why he ignores you. It happened when I was a teen, it happens now, and it will happen when you are my age.
If you get back together with this emotional numbnuts, it's likely because he thinks you have changed your mind about the "giving him what he wants." You are worth SO MUCH MORE than this, sweet girl! Wait to find someone who will give you all his heart and shout that he loves you from the rooftops. Yes, they are out there!
You may truly believe you miss the guy you dated, but I think it's the idea of having a steady boyfriend and being loved. Love yourself first and foremost. It hurts like hell to be rejected and used in the way he used you, but LEARN from it. Don't go back for seconds -- please. This guy will make you bitter if you let him. Instead, pour all of your energy into making yourself the happiest, badass-est version of YOU that is possible so that you can move on and find someone who will value what's in your heart and between your ears as much as between your legs. You're worth giving him the cold shoulder.
