Hopelessly in love

I keep falling in love with the wrong guys. My past 2 relationships were completely one sided. I loved them basically with all of my being, they were the most important thing in my life. And all they could say was stuff like "I didnt love you enough to make you as happy as you deserve to be" and "it wouldn't have worked out long term" and the worst of all "I don't have romantic feelings for you". Even though the compatibility was there, we got along really well, and he keeps talking about how important my happiness is to him. You know what I need to make me happy? All I need is him back. But he doesn't want to get back together, he thinks I deserve better. To me, he's the best. What do I do in this sort of situation? Do I just need to wait it out and hope my dreams of getting him back go away?
