I had the exact same problem at the beginning and I solved it by accident. A couple of months ago we went to the movies and watched Guardians of the Galaxy 3 (stupid movie, do not recommend). So I started crying when

that fucking cyborg rabbit died.

The dam broke and it went on for like 15 minutes. I already thought to myself that this is it. This is the beginning of the end for this relationship. But instead of getting punished for any sign of vulnerability, she took my hand when she noticed and squeezed it. She whispered that it’s ok. Our relationship completely changed over night, I changed over night, I found out what mutual love actually means, that every single relationship before that was anything BUT normal and kind of a toxic waste of my time. In my mid fucking 30s.

I understand that this is kind of a all-in situation. Eighter wreck your shit forever or change your life for the better forever. So thats horrifying. But at least you have the chance to finally quell your fears?
