I know this is a forum for your books and you but i’m going through a breakup and I need someone to talk to.  As a man, I feel like I have to push my feelings down until I don’t feel them anymore.  My girlfriend of 16 months recently broke up with me because she “didn’t have feelings” anymore.  How do I deal with this?  This is my first big relationship and it hurts so much.
