I tried a few years ago to become a vegetarian but I have no idea what im doing. My husband is a BIG meat eater and so is my eldest son, it became very difficult for me to prepare 2 meals every night. I have a hard time eating meat because I can only think of where it has come from

My husband use to hunt and doesnt now because it has caused many problems between us

When I go out to eat I order what ever I want but I always pick off the meat
I am tired of having this constant fight within me

I know there is a big difference between a vegetarian and a vegan, so is there anyone that can help me??
How do I decide which is right for me?
How do I get enough protein?
Are there ways to adapt to my families way of eating?
Thank you in advance
