Dumped GF On Valentines Day!

Women are quite bad at understanding their own emotions, and just follow what they feel. In this case it was jealousy and needing attention, but she will never say that. Feelings need to be validated, not explained. Because in a woman's world any expression of discomfort is immediately pampered by other women's attention. They can not understand that men are wired differently, and consider this as just bad behavior, and conclude that "he does not care enough about me".

Well, at least they didn't live together. He totally dodged a bullet in that case.
