Yes.. He really loves Bella.. From the sacrifices he made, especially in breaking dawn, where he actually disobey the pack just to save Bella's life.. That was really hard to do.. Not only that, there are alot of sacrifices that he actually made for Bella.
I think he always did, and always would, प्यार Bella. I think the reason he was drawn to her though, was because he was meant to be with her daughter. It was destine to be that way. Once he saw Renesmee, THAT was his one true love. He still loves Bella, just not like "that".
