DH and I haven't had a night away just the two of us. My mum offered to have the children at our house so we booked 2 nights at a local hotel, as it's DH's birthday. We were due to go this weekend and this morning I said "are you sure you're up for this?" And she said she felt a bit under the weather and could we just go next weekend instead? Well no, the hotel was booked months ago and we wouldn't get a reservation as it's v v popular. So I tried to cancel and we would have lost all the money. 
So I said to my mum why don't you and dad go? But no, she's in a knark with him and they're not speaking. Then she was all "oh just go, I'll have to manage." 
I said there was no way I could relax knowing she wasn't well and it was likely my dad wouldn't be coming either, so offered it to my SIL (who is v excited so that's good)
And now my mother is cross with me for not going and "making me feel bad" and my dad is cross that he's not going.
And my husband is cross with my mum cos he thinks she doesn't like him and that's partly why she cancelled. And I'm just pissed off.
