I'm sorry, but this act is very selfish in my eyes... I'm sorry, but that wouldn't be my first concern.
Maybe she wants to get some work done while dad rests, or maybe you're right about her wanting to be online while dad rests. Bottom line though, is that that's her business and her decisions and though it wouldn't be your first concern, no matter if you're right or wrong, she doesn't have to think like you. And WASs rarely think like LBSs if ever!
Insofar as "ending" it, don't make decisions based on emotions. You'll regret what you did, and find it more difficult to work this out. There's another member who was on course, saying his WAW was making big giant steps back, but she wasn't 'saying the right things" as per his expectations, he got impatient and served her divorce papers (acted on his feelings of frustration) and she moved out and it looks like she got more involved with the OM, and now he's regretting what he did to push her away and looking to see how he can undo the damage.
There's a lesson to be learned there about letting your emotions make your decisions for you.
