Anyone who has personal experience with a jealous, controlling man knows exactly where this behavior leads. It's the opposite of sexy.

my good, it's obvious to me I would absolutely HATE this book and the two heroes, In general I hate jealousy in general in relationship, basically I don't see the point, if you're jealous it means you don't try the guy/girl if you don't then what's the point of the relationship?
But the acts that you say he pulls sounds like the start of abuse to me...
