I've been there before and it does suck, but the best way to move on is to cut contact with him and start focusing on your own things. Surround yourself with people and activities that will keep you busy and distracted from the heartbreak you are feeling right now. It will fade over time, but you need to be proactive and start putting energy into positive things if you want to move on quickly.
Take this advice from me, because after three years of choosing guys who weren't ready for an actual relationship, this is what I have learned:
1. If a guy is interested in actually dating you, you will know. He will say it with his words, and back those words up with actions to validate what he says;
2. It's important to know what you want from a relationship and not to tolerate anything less than that. If you start dating a guy who will only text you late at night, or only wants to see you once a month, then you need to cut ties with him early. The earlier you realize someone isn't capable of fulfilling your relationship needs, the less painful it is to end things.
