We have some friends, known them about 8 months and we get on well with them and all our DCs adore each other. We spend a fair amount of time together but they can be a bit flaky/rude we think and it is getting frustrating. Things like my friend will say on message 'oh we are really missing you guys, it has been too long', I then suggest a plan to meet and she ignores me. This happens a LOT. I have stopped asking as much because of this. Months ago we had a bit of a drunken night and we were talking about Christmas Day (they don't celebrate it) we suggested they should come to us as we have no family here. It wasn't a formal invite or anything just a throwaway remark in Sept and we never mentioned it since. Anyway, last week I asked if they wanted to meet up over Xmas and they said they were free on Boxing Day. We said great, we are going to a restaurant at 12 so they can come with us to that or come back to our place afterwards. No response. I chased them up and still no response. It is now Boxing Day (we are in Oz) and we have no idea if they are coming or not. We think this is really rude, but I can imagine them thinking what's the big deal. They have form for this sort of thing and whilst it is annoying but tolerable on just a playdate type thing, on Boxing Day I think it really takes the piss. I sent yet another message, which I know they have seen, saying I really need to know if they are coming because of food and if they are joining us at the restaurant and no answer.
So am I being too uptight about plans and should just go with the flow a bit more or are they BU? If it is the latter what should i do about it? My DCs adore theirs so it would suck for them if the friendship stopped.
