I think if we're talking how many hours she should work, say, to help pay off legal bills, that were run up due to her infidelity, then yeah -- BGPs all the way. Or having to hear gossip get back to her about what she did -- ditto, that's CONSEQUENCES.
But when it comes to no-contact, I'm a die-hard within the first year or so. WHATEVER IT TAKES is my position. There are people who MOVE TO OTHER TOWNS AND STATES in order to try to save their marriages. It's not too extreme of a position, in my opinion.
