Dick move how do I make it better

[thistooshallpassffs]

dd was going to have a joint milestone birthday party. It was being hosted at her "friends" house.
Dd wanted to invite a girl "friend" didn't know so" friend" said no as it's her house

Dd left it , but was hurt. Dd got text yesterday from "friend" saying she doesn't want to do the joint party and dd can't go either.

All mutual friends are going.

What would you do? I'm thinking night in London , celeb hot spots although limited on friends who are old enough and not going out to the party

That really is a dick move on the part of the 'friend'.

I'd sit DD down, talk, see if there is anything else going on (that's caused this dick move).

As to a replacement, see what she'd like to do. A day & night up in London if she'd enjoy it (& if she's an Abba fan, the Voyage show is really, really worth it).

But something that marks her birthday without drawing attention to lack of peer involvement sounds good

Some teens are so difficult to understand, even by other teens!

ds(19) and his gf of 18 months split up, they recently got back together after 5 months apart and he has called it off again because he was out with a large group of uni friends and in that group was a girl his gf didn't like. No issues with trust as the girl is dating someone else there, just because he was in the company of someone she didn't like and she told him he shouldn't have stayed because she was there

If the story is just as you have told (are you really sure there isn't something else going on you don't know about) it is terrible/socially manipulative behaviour from your dd's friend.

Let your dd have her own party at home on another date, where she doesn't need to restrict invites to friends based on age. Don't let her lower herself to trying to one-up on making her celebration "better" to attract others to come to hers on the same day.
