Because I told her I'm never getting the vaccine, and that masks and vax passports are retarded and pointless.
I knew we always had political differences but it was never a major issue until some degenerate doctor told her family that covid was the reason her 90 year old grandfather with the worst case of Alzheimer's/dementia you could imagine passed away.
It actually hurts my soul, not that we broke up, but that I realized I spent 5 years of my life with a partner who was as lizard-brained as the rest of the 99% of the world's population.
If you had wanted to marry her, you would have asked her years ago. You really didn't, and now you both have a good excuse to move on.
Sympathies on your hurt. Sounds like you are better off, since you really don't want to have children with someone like her.
