Hate to Be That Person

I've recently discovered I'm becoming that woman who is so afraid of becoming involved with someone that I am rationalizing my fear by coming up with excuses to avoid putting myself out there..."I'm too busy." "It's exhausting." "They're all idiots."

I am also repeating my pattern of trying to maintain a friendship to a man who is unworthy. I can let him go, but I don't think I want to let him off the hook. And so, I cut off my nose to spite my face. Why?
