You will find someone even better if you are willing to learn from the mistakes you made in this relationship and not settle for less for yourself. You deserve a warm, loving, reciprocal relationship.
But first you need to grieve and get over this one. Jumping into a new relationship probably would not be the best thing for you. It's okay to feel sad. None of us ever want to feel sad, but sometime the only way to not feel something is to feel it until you are "done" feeling it. Until you have worked through your loss of this relationship.

Give yourself time, be kind to yourself as you feel sad about this loss. You will find love again.
