Flew Too Close To The Sun...
I'm a piece of shit. I wanted a dynamic that wasn't going to work.
Listen to your partner when they tell you when a monogamous person will catch feelings.
Listen to the monogamous person that you're talking to that she will eventually catch feelings if we keep sleeping together.
Accept the fact that trying to make a dynamic that was never going to work is going to end up in everyone being hurt.
You're better off alone until you really change yourself.
