Hi, do you speak to the other household to find out what the plans are for the holidays? Or does your DP just work out the dates and work out what he is doing on those days? We have a "situation" where DP asked DSC what they wanted to do so he's planned it all and Mum has already done it with them (taking them to a certain place to eat out was one of the things). I'm thinking if it's something like that then DP needs to speak to mum and arrange it between them or if he's not going to do that he can't get the hump about it when she's gone ahead and done the activity.
