This woman you were with, your ex gf, blames everything on you and takes NO responsibility for her own life, let alone her poor behavior that led to the breakup. You did absolutely nothing wrong and In fact, she used your confession against you as a weapon to vilify you.

It's hard to let go when someone defames your character to others. Unfortunately, this is all of your control. You don't have to defend yourself against her ridiculous claims - she will look like the villain and negative person by constantly talking shi*t about you to everyone else. People pick up on these things and notice who is bad mouthing and who isn't.

I say move on.... explore your sexuality, enjoy your life and steer clear of this woman. She is a toxic hot mess, as they say. No need to pay heed to someone so low and who is so toxic.
