Unwilling to loose for the sake of not loosing

So I have been looking over the last few dating experiences of my life and I had a very interesting realization.  I can't let go due to my stubbornness.  Mind you I can handle the loss it self pretty well, actually better then Ok (which fucking scares the shit out of me) yet when I am in a relationship, and I know it's the wrong one I can't let go.  I am so scared of that loss that I hold on for my dear life.  Like drowning in shallow pol of water and the only salvation is to put my foot down and stand up.  Yet, for some reason, while my brain is screaming at me to do it, my heart, or what ever it is, is telling me not to.. It's telling me give it more time, give it more juice find a way to make it work.  Lol like that damn scene from star track where capt. Kirk would scream to Scotty that he needs more power and Scotty would howler back "capt she can't take any more of this" but capt would never listen and push for more.  

May e one day I'll learn to place my feet down and save my self...
