Here's a concept. Send her blessings whenever she annoys you. Focus on you rather than her. The more you call her nasty names, the more she stays under your skin.
I did that and am peace. Yes, spouse (my way of neutralizing my connection with the guy I married) can still rattle my cage but the longer I am away from it, the better I feel.
And working out is a superb way of releasing steam. And heck.. why would you want womenfolk chasing you when you're still embroiled with your spouse. They probably sense you're still wrapped up with her in a negative sense. Who would want to touch that?
All your life you've probably been told what an incredibly handsome man you are. Use it to your advantage. Trust me the women at the gym and ever other place notice. Your looks can intimidate them or make them feel not worthy. It's amazing what occasional eye contact, a smile, greeting them can do over time. Relax, enjoy, and heal yourself.
And don't forget, you can DB your spouse with the sale of the house. "Absolutely spouse. I understand why you feel that way." It takes two to fight and as long as she thinks she's in a struggle, she'll keep going at you.
Yay, Rah Rah.. You go Rob!!! (insert cheerleader stuff.. whoo hoo!)
