Sorry about that, but I think you are right..she controls her own actions. It's doubtful that life will be better for her.
One small note as an aside. I was reading one of those advice columns in the newspaper and found it interesting that this woman was asking for advice about dealing with her current husband and expressing regret about breaking up her first marriage. She was jealous of her ex-husband that he was getting to see the kids and grandkids, and she had to move far away with her husband who cared nothing for her family. It wasn't said, but I bet she left her marriage for this OM and was finding he wasn't all that afterall. Your wife could find herself in a similar position down the line.
