Left my boyfriend of two years over veganism.
I've been vegan for over a decade. I have dated many men over my time, all of them eventually turning vegan. Usually in a matter of weeks or months. I thought it was activism! Most of them are still vegan today.
But after two years with the same man, I decided the lovely sounding future we had planned out wasn't enough. Despite him being a nice man and us sharing a well thought out potential future, I could not handle that he'd eat meat when I wasn't around.
I tried. I showed him everything. Documentaries, statistics, articles, images. I cooked and we went out to Michelin star vegan restaurants in many cities. Our fridge at home is almost fully vegan all the time (he keeps frozen fish in the freezer for when I am not around).
But at the end of the day, we didn't share the most important part of who I am: the belief that animals shouldn't be committed to a life of torture just for my pleasure.
It is hard. I move out to my own place on September 1st. But I am also... happy. Because I've further proven to myself that convenience isn't what is important. I want to live my values even if it's hard.
Edit: to be clear, he when we started dating said one day he could see himself vegan. I also told him it would be a non negotiable. He wasted my time too.
