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
