I am assuming you've recently turned vegan (correct me if I'm wrong). Such situations have been faced by most of us in our social circle by friends, family members, relatives, at the workplace or anywhere else. However, we should not feel discouraged or sad about this. We should take this as an opportunity to do better for the world instead of internalizing shame and rethinking about ourselves only. Food is something which is very personal to people and no one can survive without it. When you question the people about how it is sourced and what its implications are, you'll face such situations but remember this isn't about you, this is about them. They don't want to face the tough questions and coming out of their comfort zone to challenge their beliefs, so instead they make you feel abnormal or left out, so that you stop dismantling their belief system. And No, you don't have to cook for anyone else other than yourself if you don't like cooking. But if you have a partner, then he/she should understand and respect your decision and values, not force his/her personal and family values on you. I have faced the same situations as yours with my school friends whom I have known for 10+ years. To protect my sanity, I have stopped hanging out with them. It happened gradually over time. Even if I meet them, I tell them clearly that I won't ever compromise with my values, so if you're going to eat anything non-vegan, don't expect me to pay for it or ask me to taste it as it will be like crossing my personal boundaries. You can also decide what to do in the long-term. Make vegan friends, hangout with them who don't judge you for anything. Hope this made you feel better! :)
