Easy, right?
The real question is why you subject yourself to behavior that is literally killing you. Do you need a neon sign? She doesn’t want you. I’m sorry. But if you can’t see that, you’re really in more trouble than I can help you with.
Of course she’s not going to “discuss a divorce with you.”
You may be young, handsome and able to get any woman you want — but not if you’re married to her, you won’t. And not if you’re dead from a second coronary attack. It’s time to do the right thing. Man up and call a lawyer in the morning.
I’m here if you need me — this isn’t going to easy, but it’s going to be a LOT easier than what you’re dealing with now.
