Don't do the counseling. All stop on the relationship. Do not talk to her. Do not reason with her. Focus on yourself. You have no control over her or the situation, just you.
If you can't control yourself, your emotions, and your outward reaction to her manipulative and selfish actions by being detached and in a good mood, don't go near her.
Focus on GAL, Focus on reclaiming yourself. Go out and date 10 ladies. Go out and date 100 ladies.
Go develop some self worth. Be the spouse only a fool would leave and show it in your appearance, demeanor, and actions.
Keep your thoughts to yourself and do not, I repeat, do not talk to her about feelings or the relationship.
