Having trouble...

Not exactly moving on but I can't stop thinking about my past failed relationship (which took place a year ago). I can't stop thinking about how horribly it went, I've become bitter, "salty" to say the least about relationships overall. I've actually adopted a "men are trash mentality".

I don't miss the guy and I am certainly not in love but I keep replaying failed scenarios over and over again, sometimes I just get angry and remember him with great disgust.

I'm thinking that I'm solely doing this because he was the very last person that I attempted to build something with and I haven't met (or haven't attempted to meet) someone else so my mind keeps going back to those failed scenarios.

In all honesty, I'm afraid of trying something out with someone else. This experience scared me so much because it was the closest I've ever been to attempting to build a "real relationship". I do not want to waste my time with another loser that doesn't appreciate all that I had to give.

I've worked on loving myself so much since then and my confidence is pretty high but I just hate having these intrusive thoughts while that fucker doesn't even think of me anymore. Not that I want him to or anything, but just how could he live happily after the shitty way he treated me?

Any idea on how to finally let things go?
