Dating A Meat-Lover

I have been dating the same guy for three years now. He is a meat-lover. He complains just about everyday that I need to eat some meat. We have even talked of marriage and how we would raise our kids. This is a problem I don't want to force my children to be vegetarians. Children need protein, but I also don't want to be living off my boyfriend's eating habits of burger, burger, burger. I raise this question out to anyone married and raising a family. How do I feed my kids and how do I compromise with my husband?
