Wife Declares She is a Lesbian

[essjay]

Update
Both D's away last night. So just the two of us at home. W cooked a meal for us and we eat together. She tried to initiate some conversations to which my replies were civil but limited.
Does this give the impression that i'm moody perhaps, i ask because one of my 180's is to be less moody - confusing.
I know she was with OW yesterday pm, (it seems strange even just typing that!)..guess i reacted to that, as well as fact that she is constantly on the phone or i pad.
She seems to have this one OW and PA with her and then is still checking out what else is available on the website and flirting there.
I'm trying hard to treat her like a live in sister or flatmate.
Not easy

This morning she dropped me off at work, and getting out of the car i just said to her Happy Anniversary.
She looked at me briefly, blankly, said thank you and then got back on the phone to text somebody before she drove off.

She is so checked out of this M and relationhsip..it seems nothing i'm doing is working.
