This would be a good opportunity to bring up Retrouvaille. Because the experience you just had points up the truth -- the relationship will not get better by burying the problem under the rug. You and she need to work together to heal. You don't really know what goes on at Retrouvaille, but the people who have gone swear by it. And it helps with communication, which is something you could use improvement in. That should be all you need to say. The relationship is worth the investment of one weekend. The worse that could happen is that nothing will change.
