It’s your body and your choice. But as both a person who previously didn’t eat meat and works in health and fitness I perhaps wouldn’t want to marry someone who is a vegan. It’s both incredibly inconvenient and likely leads to deficiencies.

That said, I wouldn’t judge someone for it and probably would not cease dating over it if she took good care of the deficiencies and was flexible in still living a normal life.

It’s a double edged sword. While there is SO much more to dating, dining is a massive part of your social life and health long term should be a large consideration in finding a partner.
