To cut a long story short, we have dinner round ours with FIL, BIL and SIL every sunday and although it's really nice to have them round, now that I am close to 12w pregnant it's a bit much to prepare and clean everything even with dh helping out.
Whenever we ask her to come and help she goes in a proper strop, claims that we're accusing her of not helping but that she does (she doesn't) then says that we don't love her, hangs up on dh and texts him saying "I'm not coming".
This has happenend a few times, all prompted by "can you come early and help instead of just turning up when it's ready and complain all the time?" culminating in her dad negociating to actually go and pick her up from home so she would come; that day we'd called her in turn all day to beg her to come as we wanted to announce our pregnancy to close family, by the time they got back everything was cold for everyone and when we told her about the baby she did not show any excitement.
I know she is stressed about her parents divorce but I can't help thinking she is a bit of a princess and she should get over herself.
