Hello! Just wanted to share my thoughts on this:
Ive been dating my significant other for over 8 years, living with him for 6. Only this past Feb (11 months ago) is when I became vegan. My bf had no choice to eat vegan at home because thats all I cook, and chose not to buy or cook meat for him. If he wanted it that bad, he can simple purchase it and cook it himself. I think that is fair.
My journey has been such a beautiful one with ups and downs. I have never forced him to think the same as me. In fact, I hardly even tell him what I learn unless he asks or happens to hear the documentaries or videos Im watching. I feel like this is so new to me that I only have time to focus on myself and my own personal journey through this, and try not to worry about trying to change him and his thoughts and lifestyle.
Recently however, after a vegan thanksgiving event I went to at an animal sanctuary and brought him along (he wanted to come because he loves animals), he has started asking questions ALL ON HIS OWN. one day, he said out of the blue "hmm i need to reconsider my choices, you guys are onto something" ---and then a couple days after, he asked me "where do you get your B12?" (i have never mentioned b12 to him before ever lol). the other day, i grabbed his phone to reply to our mutual friends and it went to his browser which was on some "vegan essentials" website LOL...
Now, even if we go out to eat, he CHOOSES VEG!!! Ive never forced him nor tried made him feel bad about eating meat. He started ordering vegan food all on his own. it is crazy, and i dont ever make a big deal of it and try to downplay it even though inside, im jumping for joy.
I guess the point of this is, in my opinion and in my own experience, if you just live a compassionate life and not try to change/force your significant other, and just be there when they have questions or just expose them to things and info you are already exposing yourself to, it will come naturally.
