Update on recurring topic:
Idiot older son (now 16) has finally seemed to have a breakthrough in terms of his attitude and demeanor here and towards Wife2.0. Basically, he is no longer acting like an idiot.
He didn't offer a tearful apology or anything, but he owned up to the fact that he felt disloyal to his mom if he liked Wife2.0 and admits that he hasn't been fair to her, or me.
He also admits that a lot of the things he blamed on us were just convenient excuses for him to avoid taking responsibility.
We are on the lookout for backsliding, but as of right now he has had all of his privileges restored and things around here seem to be on the mend, emotionally speaking.
I still almost can't believe it. It has been a miserable 4+ years in terms of family life. I kind of don't know how to react to the possibility that it could be a thing of the past.
All my kids still have issues to one degree or another, which I would put mostly on how their mom has parented them and conducted herself (though I am not perfect by any stretch of the imagination), but the situation with my oldest was by far the worst and most distracting/destructive.
Keep your fingers crossed for us.
