It's odd, but once you get past that, a lot of this is good, if basic, relationship advice. Don't marry someone you don't really like, be honest, don't take your husband for granted... (though the way they put that last one is approaching Stepford Wife territory).
I suppose that from a writer's standpoint, "this is why your husband is cheating on you" is better than "this is why your husband doesn't seem to like you very much anymore."
