I will pray for you and your family. I do not know your situation, but I do know that love can be saved as long as the "3rd" person is removed from the equasion. I went lost a year ago, but I have since been found and my relationship with my husband is better than ever. We are so in love. It is not fair to the kids either. My suggestion is that you do not get mean. Try to be understanding and continue to support her and be there for her. Show her your love. Try the book Fireproof. There are daily tasks that you can do at the end of each chapter. If you watch the movie, you will understand the book. Hope this helps. God, please send Your angels to watch over this family. Bring the kids mom back home where she belongs and bless them all. Amen.
