The problem is that you still see her as your old W...
Let me ask you this:
If she would've cheated on you the night before your wedding would you still have married her?
If the answer is no, then why tolerate this behavior now??? If anything she should be more committed to you after 7 years of marriage not less!!
She is living in some half a$$ fantasy world where she is the starlet of her own little romance movie!!
Stop playing your roll and the whole script gets thrown out!
You may not want to hear this but until you are detached 100% she will continue to play games with you. Once you legitimately detach i.e. no longer "yearn" for her you will be shocked at how quickly the tables turn.
