So the subject of cheating came up with my new girlfriend and she says something along the lines of "if you do that I'll cut off your dick and feed it to you". At first I thought she was joking so I was like "don't even joke about that" but then she goes "I'm deadly serious" and "don't you dare cross that line". Now, I would never cheat but I started to feel really unnerved by this. Is this girl batshit? Otherwise she seems rather reasonable.
The thing is, I've received this threat before from a previous girlfriend. Is this a common thing?
Right now I'm just contemplating whether or not to break it off because I'm not sure if I feel safe around her anymore. Or am I blowing this out of proportion?
