Hey Lan, I am sorry. I've been too much caught up in myself and didnt read here yesterday. All I can say is that the last few days actually prepared me for this last development. I get the feeling your wife is spoiled and is after excitement all the time but she isnt willing to create this excitement with hard work within your marriage. I think that if you would be willing to let that play out again, she would again be OK in your marriage. But for how long you can do that, it's your call.
I think it is time to stop treating her as a princess and play some hard ball. I would -and ignore me please if I am out of line- set a boundary and let her know, if she crosses it, she is out. Maybe she needs some tough love to get the drama and excitement that way... Good luck Lan, take care of you, xxxx K
