I have been accused of throwing friends under a bus...and needing a theme song.
With that in mind when I say make boundaries, I meant with your children. NOT your wife in regard to your relationship. You and she are not at that point yet.
Boundaries with your children AND regrding your children...oh hell yeah.
Living in the same house... It is what you need to be a parent to your children.
HOWEVER, I do not think you are currently capable of leaving your W (Notice the W for wife, if you use S then we think son) alone. I think if you lived in the same house you would drive her nuts. More nuts than she is.
You, and yes I understand ADD and ADHD, are running around looking at all these problems, when you need to learn damage control. You should focus your will on one or two issues. Look its basic if you have a laundry list of things to do, you will not get them all done if you try to do them all at the same time. You go down the list, the important stuff first.
This is your job to do, our job is support and advice.
You have a choice.
You may not be married to your wife in 4 years, but you will always be the father to your children. So figuring out some sort of plan where you are a parent at least half the time, either they stay with you every other week or you live in the basement might be a damn good idea.
You wife might not like it, but the MLC comes secondary as do her feelings when it comes to your children. Some one needs to be a parent.
But again that is just my advice, what you do is your job.
