Failed support

So weird one today, but I was having a conversation with my girlfriend today and was hoping to start a conversation with her about findom and maybe try to gauge for interest... I'm struggling to see life without it and was hoping this made more sense. She's generally very vanilla and didn't surprise with this one. She gave me a shaming for even trying to explain it and then called me disgusting for having interest in it. I'm frustrated about the response but I wish I could say I was surprised... These are hard conversations to start and even harder when you don't get any sort of support.
