I first found this website by googling "psychopath", turns out she's not one, but it seemed like an appropriate label at the time, and that search led me into the wonderful world of personality disorders. Easy to see why those labels get thrown around in the culture so freely.
I know in the past when her & I broke up, I used terms like 'Narcissist' in messages to her. That was unfair. I am not a professional and have no right to call her something like that.
So this time around, I haven't said anything. All I know is that her decision making and thought process is a lot different to mine and I felt like the harder I worked in the relationship, the less reward I was receiving from it. Something was wrong, I think it was a lot on her side, but who knows, it could have been me too. I'm said that it didn't work out.
