MIL and FIL are separated but live in the same city, 5 mins from each other.
DP is upset as MIL has messaged him and had a go, so they've ended up rowing a bit!
MIL is upset that we visited FIL today without letting her know
... She's tired of all the secrets and lies?! DP hadn't even spoke to MIL and if he had, he would of mentioned it!
MIL was then upset as we didn't pop in to say hi to her. DP explained that we weren't down for long and had been to see his DGF and DGM too as well as FIL. We can't see everyone in one day! DD was very poorly and in such a bad mood that we had to leave early anyway!
I'm so annoyed because she's such a hypocrite! She's said in the past, that when we visit someone to not feel obliged to rush around and visit everyone else in one day. Come to visit one set of family at a time and have a chance to see them properly!
Funny how when it's not her we're visiting all that goes out the window!! 
Grrrrrrrr! She's the one to talk too! Secrets and lies?! She's the one in the past not to tell his DGM that he's visiting as she wants to see him without her being there!
It was a last minute plan to go see FIL as DD has never been to his house, no secrets, no lies! Just something nice, or so I thought!!
Arghhhhh... And breathe!
