To not let DD 15 attend 6 year old DB party
Last year I booked a little village hall party with a bouncy castle for my little one's birthday party, however my DD nearly 15 has said she didn't enjoy it and didn't want to attend a kids party again after I booked one again coming up next month. My DM who I am low contact with has reached out to DD by messaging her to go on a shopping trip with her the day before my son's birthday and said she will book the following day off (DS 6th birthday) and take DD out for fancy meal if she like to stop with her. DH is not very happy and thinks DM has done it on purpose, and that DD should be there for DS birthday party, I have spoken to him and said that DD will still see DS just later on that day. DD really doesn't want to go and said she will just hide away in the kitchen looking at her phone to avoid all the little kids. I don't believe in forcing her to come if she doesn't want to but DH said I can decide, but I don't think he's particularly happy if she doesn't attend and think she should be there. I'm just wanting some advice on wwyd in this situation?
