Absolutely second what Mackay said. In my neck of the woods a restraining order would prevent him from trespassing on your property and your place of employment but more importantly, would also prohibit him coming within a certain distance of you/your wife where ever you may be. It is also the device that legally severs that family connection - if he is served with it, it removes any excuse he can come up, if he should choose to confront you or trespass.
