Feb -
I'm not an expert, I'm not an SI vetern, I did not even get the chance to attempt R so my view may be flawed. However, for what they are worth, my thoughts.
First: There is NO acceptable excuse for having an affair. NONE. Stop making them for her.
Your WW is lazy (maybe it's depression?). Whatever the reason, she has learned from past experience that when things get rough for her she can just check out and you will pick up the slack. Her job is stressfull? You get the lunches made and kids ready for school. She doesn't like hockey? You take all 3 children to the rink. Kids are behaving like kids? You look after things so she can ride her bike.
Now she has created the toughest possible scenerio of all. Her riding group doesn't want her, people are mad, her husband has been hurt and will not allow it to continue happening...and she is too lazy to fix it. She is waiting for you to step in and make it better.
Your WW needs to be forced to wake up and face reality. Real parents parent 24/7. Through the early mornings at the rink and the snot and fights and tears - not just for the family portrait moments. Real spouses are committed to their marriage - for the laughter and the love, and for the stressfull times, the boring times, the sleepless "I hate this" times.
The thing is - you CAN'T fix this. She made the mess and she is the only one who can really clean it up. You can move the furniture around so you don't have to really look at the mess. You can put something on top of it to hide it, but it will still be there. She is the only one who can really clean it up. She is going to have to get off her lazy ass, get out of the pity puddle and do the work herself. It may be that her first step should be to see a doctor, but again: only she can make that step.
What I am seeing is that you are continuing to enable her behaviour. Think about this: She didn't want to get out of bed this morning, so you made the lunches. Did she make lunches those days after dday when you were wishing the world would just go away? You are justifying her behaviour based on her "bad" job, her stressfull kids. Really?! Have you never had a bad day at work? The last time the kids had an argument on your watch did you whip off your pants and f@ck the closest available vagina?
Finally, some thoughts on your children. I know you are hurting for them and worried. As a mom who has held her DD through more versions of hell than any kid should have to go through, I have learned this: kids are strong. When they know what they are dealing with and they have some solid coping tools, they will be ok. Really.
Your children know that something is going on. They might not know what, yet, but that just means that they are imagining all kinds of scenerios in their heads. They need to know. It can be a simplified version. But not a sugar coated one. Don't beat around the bush. That only leaves room for them to fill in the blanks with their imaginations. Tell them the truth. Then provide them with the tools they will need to get through this. You are one. Books, a councellor, the knowledge that it's ok to be sad, mad, scared - all are good. A safe place, hugs, maybe a punching bag.
Ok, end of lecture. Hang in there Feb. I, like the rest of SI are rooting for you. I would love to see one of the "good guys" win.
