My friend has a big birthday coming up soon. Her DH said he was too busy/tired et al to do anything (he's generally selfish and usually puts himself before his family's needs anyhow), her mum and I got together (and with his knowledge and go-ahead) started planning a surprise party for her. She has NO idea. She has had a rough year and deserves a brilliant surprise.
Venue booked, basic theme set, goodies being ordered. All looking good! Next step, send out invites.
Her DH suddenly charges in, and, out of the blue, wants to take over.. changes venue to somewhere cheaper (err it's cheaper for a reason...) and sends a mass invite email out to all and sundry saying HE has decided to throw his DW a surprise party, the theme is W (our chosen theme), and he is doing X, Y and Z (our plans). 
I am trying not to be upset. Her mum is trying to make excuses for his behaviour. He wants to know the contacts for the party goodies, I've told him what to google. Childish of me maybe... but I think he's being rude, and doesn't deserve any more help from us, especially when he is telling everyone he is organising it all. He booked the new venue and sent a mass email out. That's it.
AIBU to feel irritated by this? He is her DH and it's lovely he wants to do something for her party... but we have done all the work. It's the WAY he's gone about it. Even sent us both an invite hahaha... no, I am not actually laughing.
