I have read over the last 30 or so posts to catch up. Children, especially young children, regress when there is a crisis. so in that sense be wetting are normal. Acting out is also normal during crisis. However, the crisis is not normal. That is the catalyst for the changes in S7. I would recommend reassuring your children that you love them. Physically and mentally comfort them. Try to prop up their self-esteem. Children are very ego centric. They think everything revolves around them.
So they take this crisis to heart. They believe they are apart of this. Your wife telling S7 not to use it as an excuse was terrible by the way. The best thing would have been to validate and reassure S7 that it was normal and that everything was going ok.--or just not make a big deal out of it at all unless S7 seemed real concerned.
You are in a tough place right now. I agree with CaliGuy, no need to keep telling WW what she is doing wrong. It will do you no good.
Church- I to was an atheist until about 11 years ago. WW and I started going to church about 4 years ago. She stopped going and eventually I did to. When things started getting rough I started gong back to church and taking the kids on my weekends. It has helped me a lot. I also wish that WW would get to church for some perspective. I do not see any chance in that right now. Once of the best friends she hangs out with is an atheists and is very cynical about church. Her family, while they seem to be spiritual, is also very cynical about church.
