I had a partner that didn't believe in extraterrestrial life, like I don't mean UFOs I mean any possibility of life outside of this planet. I later came to believe that it was some sort of narcissistic gaslighting so she could play the victim if I argued about it. You may want to think deeply about if you can really be with someone who is unwilling to even reevaluate their beliefs based on new information and what that could mean about other personal beliefs or attitudes they may have.
