Is it a pattern?

Every single girl that i have had romantic interest or done something with always ends up being someone that has a fair deal of emotional baggage and trauma in their history. And it just does not end well, i seem to get shafted or get emotionally hurt in the process. It seems as thou i either attract these types of people or its just what fate has brought me.. Not sure what to make of it all. Maybe I look like a safe guy for these types and in some cases a great rebound for them in order to go back to others.
