I think the difference is that all animals which demonstrate affectionate behaviour and emotional attachment are those which require social and familial connections for survival of individuals and their genetic legacy. Very few reptiles have natural social or familial bonds, so the capacity just has not evolved.
But as you say, we do not know what is going on in their heads, and just because certain traits haven't developed because they don't confer survival advantages, doesn't mean that a rare few individuals wouldn't have a capacity for bonding.
