What's up with Watters?

"Some people change when they find that out, their whole way of looking at you and speaking to you changes, but his didn't."
How I Met My Husband, pg 135

How I Met My Husband is told from the point of view of Edie, but Chris Watters is the character I would most like to get to know. He seems to be an interesting guy; he treated Edie with respect and courtesy at the beginning, even after finding out she was the hired help. However, he fails to mention that he has a fiance, which is something any faithful man would be expected to say. Then, his attitude towards his fiance is one almost of indifference, and he kisses Edie. Leaving her with the hope of a letter may have turned out for the better for her, but seems cruel to me. So, is Chris a good guy or a bad one? I think he's not necessarily a bad guy at heart- he doesn't seem to purposefully hurt other people. It seems more so that he is too involved in himself to realize how his actions affect others. His treatment of his fiance is obviously bad, but he treats people in general with respect. I wouldn't want to be in a relationship with him, most definately, but he might not make it onto the naughty list yet.
