Your husband is a people pleaser, therefore really couldnt get his needs met in your marriage. Perhaps the reason you are going throgh this is so that BOTH OF YOU come out of this together as better people more in love than ever before. You don't want your old husband back. You don't want to be your old-self anymore. You don't want to set the clock back to the same old same old.
In addition, you don't want to move the clock forward without the changes taking hold in you and him that this crisis is bringing out. Gold must be refined in FIRE.
Yeah...well that's, at least, what I tell myself. ;-)
The thing about people-pleasers in affairs is that they won't get out until the pain is too great for them to bear anymore. He's feeling it big-time already. The OW is pouring on the misery by the boat-load. Let her be the drama queen.
