Take time for yourself. Finish grieving over him. You may feel like he did not value what the two of you had but that is his choice. Take time and slowly get back into dating when you feel the time is right.

It will help if you realize that you don't necessarily have to stop loving him. He was a wonderful chapter in your life (hopefully). Enjoy that! You don't have to erase it, deny it, or put an end to it. Just move forward one step at a time. You can love someone and still let them go.
