Call me delusional if anyone wants to you are delusional , but I dont think she really wants to be there what's the reality? ,but see's it as her only option right now mind reading . She CANNOT support herself or the kids no she has a job, admit it , and the prospect of seeing her twins all the time ( as opposed to 1 weekend a month when we were together) being dangled or used as a lever how about she is having an affair and wants to be with this guy instead of you , combined with her feelings about how much I hurt her made it "tolerable" in her mind, at least for now or at least as long as you keep your current thinking up .
If you truly want to understand your wife stop thinking like a man. Until you understand how and why she feels the way she does you will remain stuck.
I know you are trying. Change your thinking, promise it will help you.
Cheers
NO Coach, she DOES NOT have a job. I know this for a fact.
As far as her not really wanting to be there goes, its not so much mind reading as what she alluded to.
