MMF, I think you should read Ed Wheat's book "How To Save Your Marriage Alone". Very easy read and biblical, and it will give you some very good pointers on how to win her back. It's a very thin small book too. And in addition, check out "The Love Dare" book and "Love & Respect"!!!
As far as you daughter goes, I think you did great in letting her and you W have their way. It shows that you are willing to take their wishes into consideration.
