Recently went full time.
Have 3 grown up ish kids who rely on me less and less and the weekends (EOW) are my solace atm.
2 DSDS who come home with DH EOW.
While ago DSD1 13 bought a friend and asked a few weeks in advance which was all fine (until after we let them sleep in the same room ex wife told us it was actually her girlfriend which I was furious about but that’s another thread).
Two days ago “D”H informed me the friend was coming again. I was going to say you should have asked me (as I do all the cooking and I am knackered atm with a huge workload).
Also possibility we may have to have the family pet put down this weekend so bringing a guest was really really not a good time.
Went shopping on way home cooked tea which wasn’t ready till 7:30 and then suggested to DH he should have checked with me about the friend also coming.
Then he had a go at me for dinner being so late 
Friend came with pocket money and they want to go to the shop to buy “snacks” and come back with 10 tonne of chocolate.
Ask them to clear up after dinner and DH after being totally draconian with my kids doesn’t want to have to do that and asks me to go and do the parenting and tell them
all to have a shower because all three smell badly of BO and he even said he had to air freshen the car on the way home.
I should not have to parent his kids
