Heartless?

Okay I will admit to many things but being heartless is not one of them. Why do some people think of me that way? I realize that I am not a highly emotional person, easily offended person, touchy-feely kind of person and I don't consider myself a romantic person either but heartless I am not. I would go to the extent of saying that I am a passionate person, even a dramatic person I just don't understand why people think I'm heartless.
I don't like Taylor Swift songs, I don't get into romance novels, I can't understand what girls like about getting cards and flowers but there is a heart that beats in my chest. Tough life experiences may have hardened it a little but none the less I do have one.
I once felt the tingle in my spine when I saw him, I faught the urge to throw my arms in the air and shout when asked me out. In fact I couldn't stop smiling for hours on end just thinking about the fun times we had together. But once I found out that he had lied to me, went behind my back to do forbidden things and said things that hurt me or embarassed me; it was over. It took a long time for me to move on, but I did. I found someone else and they manipulated me and once they were ready to move on to someone new, they just dumped me and expected me to hit the ground running on with my life. My hurt feelings meant nothing to him. This pattern continued until I wised up and started learning that my heart didn't belong on my sleeve, it belonged in the intermost part of me where it would be protected from harm.
That is why guys don't get hurt so easily, they don't put themselves out there and take themselves so seriously in a relationship. So I started thinking more like a guy, that's all. I never had my heart removed as some people think, I just changed the way I precieve people and situations. I am more realistic and practical. the only time I think in fantasy and dreams is when I am on vacation at Disney World, then I let myself go.
