I heard this once and it really is profound :

I'd rather be alone and healthy, than ill with my spouse.

Think about that.

It's terrible that she's only giving you those two choices, but at the same time she's making the choice very easy.

And sometimes MJ... SOMETIMES, you chosing to be alone and healthy motivates your spouse to join you.

But you can't do it looking over your shoulder. Do it for your own respect and dignity. You reclaim that, and she may join you, or she may not.

Dignity is the cake MJ, she's just icing. If you reclaim your dignity and she doesn't show up, then so be it... It's her loss.

Do you know what the success rate is for what she's doing? Like 2% of affairs succeed long term. It may take four years, but one of those two will cheat on the other eventually. There is no honor among thieves.

YOU need to get away from that. If she's smart, she'll join you.

If not, you are better off without her.
