I feel you, when I shared my story with my "ex" feminist girlfriend who actually did outreach for women and rape.
When she told me that I couldn't be raped as I was big bad man.
I am a feminist now, and I have one person in my past (who isn't my friend) to thank for that.
So I 100% empathizes and sympathize and get 110% how it sucks to not be believed and have it fester in you.
I am glad you are healing and be well!
