Don't doubt yourself on this journey. It doesn't matter where you've come from or what you've been through. It doesn't matter how many times you feel you've repeated the same mistakes or how many times you've attracted the same type of guy. None of that matters.
What matters is how each experience brings you closer to what you're really looking for. With every heartbreak, with every disappointment, you learn and you grow. You get to know yourself better and you get a clearer sense of what you're willing to put up with and what you're going to be picky about.
You learn to be more flexible in some areas and less in others. You learn what feels good and what feels awful. You stretch, you constrict, you ebb and you flow. You see things more clearly; the fog lifts just that much more.
You start to learn that it really does matter that you know yourself well enough to know who it is you're really looking for. Your list changes to reflect the you you're discovering and learning to embrace in love. You revise it to reflect what is most compatible with the real you and not some version of yourself that you thought was really you. You begin to understand why being emotionally available and having the ability to commit to a real relationship are the number one and two must-haves on your list. You begin to see why how he treats you matters more than any item on your list.
You stop making excuses for anyone. You start rightly expecting him to pull his own weight and refuse to keep anyone around who brings you down. You stop expecting someone to complete you and make your life over and instead, you realize what you most want is someone who is a real person who you can have an honest, open, loving relationship with. You start living in reality instead of the fantasy that felt so familiar because you thought you needed to be rescued. You finally see that you don't need anyone to come and rescue you; you hold the key to your own happiness.
You stop beating around the bush and you start coming right out and saying what it is you're looking for. First to yourself, and then to him. You begin to really get that it's only by communicating honestly with any potential new guy that you can both find out quicker if you're on the same page or wasting your time. You stop pleasing. You stop placating. You stop being whatever someone else wants you to be. You stop living up to someone else's unrealistic expectations of you and start listening to that soft inner voice that knows you better than anyone else.
And this time, you actually believe it.
