Deployed Soldier/Father needs your help

[SoldierDad]

Great advice all. Well, just woke up to my S12 calling me. W has left the building again. W lied to S12 that kids under 18 couldn't go to certain concert, then lied to him, that she wasn't going to said concert, but had t-shirt on with the bands name on it when she left the house. He told me "D, I know she is going to that concert, and I really wanted to go, M knows that that band is your favorite, and mine too, why did M lie to me?" What do I say to my S? I just told him that your M was not telling the truth. S12 has seen videos of said band, with children all over the audience. It's just sad what she is doing. My S doesn't understand all of this, and told me tonight he feels like yelling at her for the way she has been treating him. It is sad and pathetic that my 12 year old son, has better morals than my 38 year old W...
