Hi she is not feeling "it" anymore

[Mrrch]

This morning she texts me from the basement about doing groceries as a family as she needs some business groceries as well, I politely decline and say I will do groceries and she could pick up her own.
Later we head to her sister's house as a family (my son asked for us all to go)
SIL is aware of our switch.
On the way out my wife ignores an out of town call on her cell phone (new vehicles are great) I don't recognize the number but memorized it.
I did not react,did not obsess about it (I did google it though)
She still talked about the summer with her sister (including me in the plans)
I have to play cool and stay detached
Admit her behaviour has me confused at times but from what I have read it is the norm for a WW.
