D. Inconsiderate. Past girlfriends had previously called him "insensitive" which means that his word/actions can also be considered as a lack of sensitiveness or understanding.

Some people are insecure, or downright untrustworthy of their surroundings. Usually, it's not your fault if they are fake towards you. They have usually adapted their fake selves on others that it becomes a normality.
Hope this helps!
