Does it inconvenience you in some way? It clearly affects her job and remaining silent or not even texting seems kind of silly. You can be dark but it's sort of a rule to always answer things about the kids.
I don't get why you see this as her being selfish. You said it's "always about her" but isn't it about the kids AND her job commitment...?
how's that selfish? And why else would she contact you at this point?
I must still be missing something. "helping" her out in this situation is NOT you being a doormat.
It's just cooperation between adults with kids and jobs. If it's a hassle for you then I guess she can hire a sitter?
Is that better to you? I'm just asking.
