Feelings

Is it possible, that after all these years and everything that has gone down between Mr. Big and I, that he might not have feelings for me?

He admitted that he does and during our most recent round of arguments, has taken that back.  And while to some extent, I think I can understand why, after all, he IS technically "married", albeit, to a golddigging bitch who doesn't care about him, and if he continued to admit his feelings it would cause more of a problem for him, but is it possible that someone could be that heartless and that awful of a person that they spent years and years and years with someone and not care about them and not have feeling for them?

Seriously, is it humanly possible, for someone who says he's a good guy and that he cares about me and wants me in his life and was terrified of losing me and was "protecting" me this entire time to not have feelings for me? 

Could he really be a heartless bastard?
