Posting here for traffic mostly, but I guess it'll have a hint of 'tell me if I'm BU' to it...
DH and I were looking to head out to lunch last weekend without the DC's for some 'couple' time, and seeing as we always rely on my family to help us out, I suggested it'd be nice if MIL could actually help us out for a change + she'd get to see the DC's who she only sees maybe twice/three times a year despite living 10 minutes away (that's a whole other issue) ....
Anyway, DH contacted his DM, she responded saying she was busy last weekend but could do this Saturday. Great, we thought, we'll take what we can get! Have spent all week looking forward to a few hours break with DH, only to find out that my MIL has been ignoring all messages from DH regarding babysitting since Wednesday  She's an active Facebook user, has posted multiple times while DH has tried getting through to her, but she's been reading his messages and just not responding.
DH is understandably fuming that his own DM is just straight up blanking him to get out of watching our DC's for two hours, but he's not (and won't) say anything to her or pull her up on it.
It's now 7:30 on the day we're supposed to be going out, and we've still no idea if we're actually going to be able to do anything! If she couldn't do it, or even didn't want to, is it not courteous to simply say 'no' as opposed to ignoring someone you said you'd help???
I feel like messaging MIL and asking her to please let one of us know if she's actually going to help us out, as the blatant ignoring is just shitty! But I don't know what best to do or how's best to deal with this?
