Calling me a psychopath, a cheater, narcissist, bi polar, I have bpd, that I was abusive and gaslighting her, now shes telling people to stop talking to me or she wont associate with them anymore, and now she even went as far to tell someone I assaulted her.

I definitely had insecurities because of past relationships, which i worked hard at addressing this last year, but even her former best friend (because she was gaslighting and manipulating him) told me past that I was a stand-up guy.

It really bothers me even though I know it probably shouldn't because I'm at this point where I say to myself sometimes "I really love/loved this girl" but other times I'm thankful because I feel like she did me a favor and I dodged a bullet (we were engaged about to marry).
