<human>: I know what you're thinking, reddit.  I'm some girl that's upset because she just found out that her boyfriend/husband was cheating on her.  In this case, I've recently found out that I was the "other woman."  

But, it's more than that.  This has happened more times than I can count.  With the exception of (maybe) three lukewarm dates, any guys that have pursued me have had girlfriends or broken up the day before (usually the former).  I'm never aware of this, and wouldn't think of getting involved with someone who wasn't single.  And I always find out in a horrible way.  

Finding out you're the other woman hurts more than I can say, especially when you really like the guy.  It's a mixture of what, I imagine, it's like to be cheated on and shame.  Somewhere there's a girl who is going to be hurt if she finds out about this.  I always feel dirty and used.  At the same time, I have the label of "the other woman," so it seems like my feelings don't matter anymore.  I'm just that "slut" fooling around with a girl's guy. 

Because this has happened *so many* times that I am beginning to feel this has to be my fault.  It's like I have a sign hovering above me that says "Looking to cheat?  Use her!" I'm trying to figure out what it is about me that lures these unavailable men.  Trying to comfort me, some of my girlfriends say that I'm just too "chill and relaxed" which is appealing to guys if their girlfriend is naggy and/or bitchy. 

So, men of reddit, if you've ever cheated on your significant other, what was it about the home-wrecker that drew you in?  And what can I do to stop this from happening any more?  It just makes me feel like a bad person.

Summarize the given text in a few sentences.
<bot>: The only guys interested in me are the ones looking to cheat on their significant other.  What's the matter with me?
