If I found I was getting the same results over and over again, I'd ask myself.. is it me or is it them? Since the people change, I'd figure it was me that was drawn to this type of behavior.
My next question would be what would I do about it? In the past I'd connect with men who would eventually withdraw emotionally and never seemed to like all of who I was. At times I'd probably even qualify as batchitt crazy because I was so needy. And why was I needy? Because I chose men who wouldn't or couldn't give what I needed.
Now through this process I've learned I'm responsible for my happiness. I'm responsible for my choices. I choose how quickly I connect with a man. I'm responsible for the consequences. I choose the level of involvement.
So.. I guess what I'm dancing around is.. If the same thing keeps happening over and over to you, you're doing it to yourself. You can continue doing what doesn't work and/or try something different.
