I am feeling really upset and furious with DH right now but not sure if I’m totally overreacting. I need a rant but also some impartial opinions.
Married 9 years. We have DDs 7 & 5 and twin DSs 22 weeks.
I say this because I think it’s relevant to explain my feelings: DTs were not planned. DDs were out of the baby/toddler stage and a bit more independent, we were comfortable with money, felt our family was complete. I was a SAHM but started back at work which I was really excited about! I had been working 5 wks when I found out I was pg 
A few wks later we found out it was twins!
Despite the problems we chose to go ahead with the pg and obviously I’m so glad we did, we all love Dts to bits and couldn’t imagine life without them! However I have found it difficult to go back to the baby/SAHM stage, and 4 children is a lot of work! DH has a fairly demanding job and is out of the house from 7am to 7/8pm most days. He also has to do overnight stays (1 or 2 nights) sometimes. This is about twice a month. He is a great dad and v. hands on with DCs at wkends.
Now to the problem: DDs have been asking to get a dog for a few months. I have always said no. I like dogs but right now I think it would just be way too much work. Who would walk it? DDs are too young to do it alone and I don’t fancy struggling with a double buggy and a dog every day on top of everything else. Plus dogs cost money (food, vets bills etc) we are managing atm but don’t need any extra strain on finances. DDs insist they will take responsibility but the same thing was said about the rabbit we got them the year before last. Guess who does all the cleaning out and feeding? [hmml]. I just feel like a dog would be a huge extra burden on me that I really don’t want right now.
I thought DH and I were in agreement on this bt today he took the DDs out for the afternoon. When they arrived back DDs burst through the door full of excitement and announced to me that we were getting a puppy!!! Apparently they had bumped into a friend of ours and DC at the park and gone back to their house to see the puppies their dog has had. Friend is looking for homes for the puppies, DDs asked to have one and DH has said yes! He says the DDs really want one and it will be nice for them and he thought I would be pleased 
I am furious! What the hell was he thinking promising this without talking to me first? And not just any dog, a fucking puppy!! (Which will presumably need housetraining, etc) He thinks I am being a misery and it will be fun to have a puppy, but he just. Doesn’t. Get. It. He is hardly ever in the house during the week so it will be me dealing with it whilst looking after 2 young babies, taking older dcs to and from school, cooking meals, looking after the house and doing all the other jobs that he seems to think are done by the fucking house elves 
We are just not in a position to take on this puppy but the DDs now think they are getting one and are so excited. They are going to be heartbroken 
. I know we need to tell them sooner rather than later but DH is refusing because he thinks I will come round! I should tell them but that’ll make me the bad guy yet again (lovely daddy says we can have a puppy but nasty mummy says no )
DH and I have had a big row and I’ve shut myself in the bedroom to feed the DTs and have a good cry. I just feel like he doesn’t appreciate how hard it is with 4 children all week, and the sacrifices I have made for the family. The fact that he can think nothing about piling more work and responsibility on me makes me so angry. I know he doesn’t mean to upset me but he just doesn’t think. He will bugger off back to work tomorrow and leave me to deal with the fallout.
I am so upset, but am I overreacting? Its hard to know whether I’m just overly tired or projecting my frustration at being a SAHM again (my decision and the right one but not what I planned for this stage in my life)
Any honest opinions welcome
