No apology necessary. We are here to help one another.
I completely agree with Trent. If you have had a discussion with her before, you don't need to go back to the well on that.
You really have to focus on you right now and your R with your kids. Your W probably has some legitimate gripes (it's never one person), so look at what you need to change. But do it b/c YOU want to do it.
And, just like Trent said, don't believe anything she says and only half of what she does.
