Clearly you were taking orders from your heart and not your brain when you hooked up with your previous amours, because you chose folks who were rather ill-suited for you on paper. You're not the clearest thinker on the planet, and your lovers were a bit, well, wishy-washy. Not able to marshal your decision-making functions particularly well, you and your lovers were happier sitting in a quiet corner dreaming the day away.
Your dreams never seemed to make it off the drawing board, not to mention your constant spinning-your-wheels M.O., which made you both discouraged and difficult to live with. And this is true of you to this day, not just in relationships.The answer lies in confronting your patterns and in being brutally honest with yourself. Haven't you been having the same conversations, the same tedious thought-loops in your brain, over and over again? Stop repeating yourself, and stop imagining that simply by continuing to live in la-la-land, things will change. The time has come for creative thinking, new ways of tackling the problems you face. Try something new, because what you have been doing certainly isn't working. Look for someone a lot more sensible than you are to keep your feet on the ground.
