Some thoughts to ponder...

Don't fear to give love. Still love as if you've not been hurt before. I know that it wont be easy. We tend to guard our hearts each time, for fear of getting hurt again. But sometimes, we need to take risk, just like what we did in the past. Don't be afraid to love again. It is not your fault that the other can't love you as much as you do. And, it does not mean that you're not lovable too. Maybe, its just that the other find his love inadequate compared to the love that you have given. Maybe, he thinks that he doesn't deserve you at all. The failure of others to love you won't make you less of a person.
