Happy Belated Birthday, KAW! It's my Nana's 91st today.
The naked room mate thing...curious. But then all through this "that" part of your R has held strong, hasn't it? Wouldn't it seem strange for her to suddenly start dressing for sleep? It's so hard to say what is or isn't "normal" in so abnormal a situation!
I think it's great that OM is definitely out of the picture. Yeah this all likely SUCKS for his W, but it's probably better she know, huh?
KAW, hold strong. Whether it's with CAW or not, you WILL be loved as you deserve to be loved.
