Always Brokenhearted
When you would rather be with someone—anyone—than with yourself.
Psychology Today
... responsibility.
It's time to pause and reflect on your own actions. You need to expose and challenge the very unproductive beliefs you are now operating on without being aware of them. Ask yourself some questions and keep peeling back the layers of answer until you are realer than real with yourself:
Where did you get the idea that it's OK to be with "men who are not good for you"? What were the men like in the family you grew up in? Where did you get the idea that you don't deserve to be with men who treat you well? Do you somehow think they are not "real" men? How were the women treated in your family? What did those women tell you about men and about relationships?
What do you think will happen to you if you don't go out with anyone for a week, or a month—or a year? What is the worst thing that could happen? What is so terrible about being lonely? What are three things you could do when you feel lonely that would make you feel good (see a funny movie? join a book club? go contra-dancing?) Make your own list so that you actually have some concrete ways to spend your time.
Whether or not your current partner happens to be good for you, you must first understand your own self-sabotaging beliefs before rushing into any relationship. Then you will be free to evaluate him (or anyone else) on his merits and decide whether he's worth spending time with.
