To be really pissed off with SIL

[grumpyoldgitagain]

So my SIL has asked my DW (her sister) to look after her 7 month old, for a few hours this Saturday afternoon, both of his nieces (8 & 10) have been looking forward to it all week as they love seeing him and playing with him. So yesterday she has something come up with work and now has to go down south a day early and that would mean he was here all day.

Except SIL has now decided that my DW despite having 2 children of her own wouldn't be able to cope with him all day without me there (me and BIL are out together for the day and I am the SAHD)

I am so pissed off with her for being so thoughtless and hurtful, my wife is upset and we haven't told the girls yet that there cousin won't be coming for the day tomorrow as we didn't want to send them to school upset

In case you are wondering who is looking after him now, there freeloading lodger who can't do this, can't do that as his health is bad and they are always moaning about still being in there house

AIBU to be really pissed off, feel really insulted on behalf of my DW and feel like telling SIL to fuck right off

I think you are massively overreacting

the OP said he feels really pissed off, feel really insulted on behalf of my DW because his wife's own sister has acted in a thoughtless and hurtful manner. she didn't even have the maturity to tell them herself that she'd changed her mind - she let them find out via a third party - and she's upset not just his wife but his children too. so far she hasn't even acknowledged her behavior or apologized for it.

so how is OP 'massively overreacting' by feeling the way he does rookiemater?

I think your dw should ask her sister why she is not deemed good enough or capable enough to look after her nephew.

Maybe she didn't want to inconvenience your DW? Perhaps she thought your DW would be put out thinking she was being used as free childcare whilst SiL worked? That it was okay if just had an afternoon event but not work? I think you're being a bit harsh on your SiL but I do understand the disappointment.

op is being 'harsh on her' for having feelings in response to her behaviour?!

that's a new one!

YANBU. Whether your SIL changed her mind or not, she was very rude for not telling your wife herself and leaving it to her mum. I wouldn't bother doing favors for people who are so poor at communication.
