I am one of those parents myself. My husband is an anglophone. He doesn't speak a word of French. We've been together for 20 years, so he doesn't exactly pick up French quickly.
As a result, the entire task of raising our children in French in a minority setting rests on my shoulders. It's not always easy. I have a life partner, but when it comes to educating our children in French and exposing them to francophone culture, I am all alone.
