No amount of strength can heal a broken heart

Apparently I have a huge sign on my head that says, Ladies take my heart and step on it and drive over it and crush it. Two years to the day that a girl i loved so much broke my heart, another one has done the same. How could i be so vulnerable to listen to the lies and let my guard down so much only to have the same thing happen to me over and over again? All i know is i'm done with it. From now on the gym is my GF. It's the only one that's never lied, that's never cheated, that's never hurt me except for the post workout soreness. I put everything i can into the relationships i have and i keep getting kicked in the nuts. And of course at the end of the day, after all the tough guy talk, i end up in tears, my heart hurting much more than it has before. God help me as i start off another year without someone to love. I just don't understand how people can be so heartless, so selfish and so cold after seeing the hurt they caused someone else. Life goes on for me and eventually it will have to forgive those who have made living it so hard.
