If you have parameters that are important, you need to communicate them at the beginning of the relationship - not in the middle when you start feeling threatened like he did. That way she can choose whether she wants to enter into a relationship with someone with those parameters. Pulling that kind of a stunt where you try to limit someone's independence after they are already invested in a relationship with you is a classic domestic abuse maneuver. As a couple of UK commenters have noted, it's actually illegal in the UK to do that - because it's recognized as part of an abusive paradigm.
