I wanted to add something about your wife being cold...
It is tough living with the MLCer, no doubt. And their moods are going to be all over the place - pay no mind - keep reminding yourself it has nothing to do with you.
Oh they'll come up with ridiculous things to try to pick a fight with you about - one of my favorites was that I didn't put things in the recycling bin correctly - but don't take the bait.
Now as far as starting conversations... I think there is a difference between ignoring and being disinterested. You want to go for the latter.
If you are slinking around your home with a scowl on your face, obviously not speaking to your wife on purpose - that is ignoring, and I do not recommend that.
BUT... if you go about your daily business - watching tv, eating, playing with the kids - being happy and seemingly unphased by miss moody- that is being disinterested. And being disinterested will help you detach.
If she tries to talk to you, of course politely respond. Then go back to whatever you were doing.
I get everything about the texting, believe me! But you can't control it. Sooo, you have to control your response. Leave the room when she texts - show her you don't really care, but more importantly, do it for YOU. You have way better things to do than fume over her texting. If she wants to be secretive, let her. If she wants to give you silent treatment, let her.
But don't let her bring you down.
FY is right... Act "as if" no matter what her mood.
Hope this helps
