Have you ever gone out with a true believer , you hit it off. Then out of nowhere they call you the devil and block you and never talk to you again ? Yeah it's happened to me more then once.
In my experience anyone can do that, believer or not. Assuming you accurately recognize and own your own role in this, if any, then then what's left is their role ... in general they are doing you a favor by not concealing their emotional labile instabilities and their willingness to pursue a scorched earth policy in litigating their concerns. This allows you to disengage before you're fully pair-bonded.
And no I am not applying a different standard here than I would to a man, were I a woman. Women and men alike are allowed to feel what they feel but they are not relieved of the obligation to "fight fair" and be kind and respectful.
My ex was a Catholic (non-practicing at the time). Strange that she started going again every Sunday since she cheated on me. But that's okay... The priest forgave her. (As did I) But we were okay with how things were.... We would have general discussions from time to time but they never got heated.
I just checked the list... Of all the things I have ever been called... Never once have I been called the devil. Lets see... Dickhead, asshole, mother fucker... Nope.. Devil isn't there.
Anyone of extremes can be a turn off. I was dating this one girl a little over a year ago. She was beautiful with a perky personality and I was excited about what could be. Then she got sick and refused to go to the doctor... Saying she could cure hersellf with herbs only... Her sickness just got worse. I eventually broke it off.
There was another I dated a few times... Then it came out that she could actually control her surroundings! Tornadoes couldn't touch her as she could will them away. The ants could not come in her home as she mentally put up a barrier they could not pass. Yet when she came out here to visit... She was constantly worried about being eaten by a bear! (Black bears don't eat people!) Oh... And she was terrified of spiders. I just stood back waiting for her to blink like Jeannie. Uh... It didn't work.
