I know a divorced man who searches for his dream partner. By choice, he has repeatedly dated women who don't seem to meet his ideals. His pattern has been to see multiple women at the same time because he fears the one he starts out with won't work out. Just as he predicted, things fell apart. The others broke it off as well, after learning that he hadn't been loyal, honest, trustworthy or faithful.
Whatever the nature of your personal life, your self-image is conveyed in your thoughts and behaviors with others. You do this consciously and subconsciously. Your true feelings will be mirrored back at you by your dates or partner(s). You may seek to avoid relationship failures yet, still invite them in. Its never too late to learn what it takes to develop your faith, renewed courage, confidence and self-love.
1) Stop assuming the worst. The Law of Attraction tells you that you will get exactly what you wish for. Buying into fear of inadequacy, unworthiness and rejection will invite what you don't want. You may need to work through unresolved, emotional wounds to let go of the past. You're never upset for the reasons you assume.
2) Address honestly your ego-based beliefs. You may feel confused about your results or the reality of what minimum success you permit yourself. Rather than sense break-ups are evidence of your faults and weaknesses, or evidence of you as victim, choose instead to examine parts of yourself that are willingly given or withheld. Facts are non-emotional. What you give is what you get. Your soul echoes its safe to give all of you. Yet, caution doesn't mean you can't open your heart. You only fear intimacy until you stop fearing your own vulnerability.
3) Identify what you desire to manifest. Superficial appearances aren't what your soul truly craves. If you believed you deserved a joyful, loving relationship, you would have one. If you believed you had "the right stuff," then the compatible person would arrive. If you don't feel you're ready, it implies you may be risk-averse or fear commitment. Learn about what makes you tick and what you can do to attract that.
