In October we stared booking a holiday for the summer this year. we said all of DCs could bring a friend, DSs decided to invite their girlfriends, DD1 didn't want to bring a friend as she just enjoys spending time as a family and DD2 had invited a friend.
At the time there was a few problems with DS2s girlfriend coming, she didn't know if she would be able to afford it or whether her parents would let her come as they kept changing their mind at the time. DD2 was also very unclear on whether her friend would be coming and I never got any replies from her mum when I texted. We went ahead and just booked without them but let them know we could add to the booking if they did decide they were coming but it would add £50 pp on.
Last Friday DDs friend slept over and they talked about the holiday and told me she really wants to come but she would struggle to be able to pay for it all at once. She's been a friend of DDs for years and I know her mum very well so DH said that we would pay the full amount now and they can pay us back as much as they can over a few months.
DS2 then starts kicking off because his girlfriend can't come it isn't fair. I am happy to have the same arrangement with her and have explained that but for some reason that isn't good enough for them and I guess they expect me to just pay for it! They've now decided if she can't come DS1s girlfriend shouldn't be allowed to come, she has already paid though and there have been no issues with that so I'm not willing to tell her she is uninvited.
Now DS won't speak to me and has been at his girlfriends all week, any time he does text me it's to have a go about favouring other DCs over him.
I just want to say to him fuck off, we are doing something nice and he's ruined it and now no one can have any friends to come!
