Bf moved in a roommate, am i in the wrong for being aggravated?

So my bf and I who have an almost 2 year old toddler together have lived in an apartment for 11 months. It’s a 2 bedroom and I assumed he got the 2 bedroom that way our toddler would have his own room. I constantly tried to turn it into his room but first he wanted it to be a “gaming room” then a “hang out room” etc but nothing ever got done with the room and it ended up just being a “spare bedroom”. Well one day a couple months ago he randomly told me that one of his buddies and his girlfriend had been evicted and that he gave them the spare bedroom and they moved in the same day. That really bothered me because for one I begged him asking for months to turn that bedroom into our sons room so he would have his own area and he never did but turned around and gave it to his friend in a day without his friend even having to ask, and two most importantly he didn’t even talk to me about it or include me in the decision to move them in. He justified it by saying it was only temporary and that they would be paying half the rent and utilities until the lease is up and that would help us put more money back to move. So I thought I could deal with it since the rent here ALONE is over $1,300 a month. He said he was just helping them out and that they would only be here until the lease is up and have to figure something else out after that. So now the lease is up at the end of this month and we’re not resigning because we’re tired of living in apartments. I want another baby and have mentioned eventually growing our family when we first got this place almost a year ago and after talking we agreed to not have any more children until we found an actual house to settle into and got out of apartments so after months of looking we finally found one that’s a lot more affordable and even has a front yard backyard etc. I have been so excited to make this new place out home because the holidays are coming and I was under the impression that it was just going to be us moving into the house because that’s what he told me from the get go, but earlier today he told his friend that “we all” need to start packing this week to all move into the house. I am honestly furious and not even looking forward to it anymore because he has once again made a huge decision without including me and I feel like it’s not fair to me and definitely not fair to our child because it’s technically a 3 bedroom but the 3rd bedroom needs fixed up for a while so our child will again not get a bedroom. It’s been so overwhelming with our son not having his own area to play and having to stay on top of him to keep him out of their things and keep him out of their room and the apartment stays a mess because they don’t clean up after themselves and the girlfriend works night shift so she sleeps during the day and I feel like I have to keep my son quiet we stay cooped up in the bedroom all day it’s just too much for me now it’s gonna be the same issue at our new house. And with holidays coming up I wanted to spend them with just MY family not my family and HIS friends because there’s no telling how long they’ll be staying. This also makes me second think having anymore kids because for one there will be no room now with 5 people living in the house and 2 I’m tired of him making these big decisions and not even thinking to include me and how it will effect his family. His priorities are all out of wack and I’m tired of it. What should I do ? I honestly don’t even wanna go to the new house now. I feel conflicted because part of me feels like he’s more worried about helping his grown friend out instead of focusing on our family because this house has been a goal for us for a long time, but I know him and know that he probably really is just trying to help them and doesn’t know how to tell them they can’t come when we move so he’s maybe trying to avoid it altogether by just letting them come to but idk.
