What can I do?

Question

Not sure how I can fix my current situation.... me and my partner been planing to live out for a while which we finally are tomorrow , well now his entire family want to move in because it’s their grandparents house which they left for us and our growing family .... they put me and my partner in the smallest room and not even a mini crib or pack & play can fit there ... my partner won’t tell anyone we need the room for our baby because we haven’t announced it yet . I’m getting frustrated because I bought his mom a bunch a food so we can talk about if it over breakfast and he didn’t tell her a thing . So now tomorrow we will be moving into a small room that doesn’t fit our baby and he’s not man enough to talk about it. What can I do? He’s pissed at me for being mad at him !!!
The house was left to my partner to pay a little under 4k rent monthly because they’re leaving back to their hometown 15 hours away . His family just decided because it’s “grandma and grandpas” they can feel free to come in which was left for us to have a family.

Answer

Op- what happened? Gotta provide us an update!

Answer

Wait, so you and your partner are the ones paying 4K/no I’m rent and you’re letting others who will also live there (are they paying and if so how much??) decide which room you get? This needs to be addressed like yesterday. Not kidding! Whoever is paying the majority of the rent should get first pick of the room- doesn’t matter who has a bigger family etc. 
If that’s you and your partner, just say which room you’re taking and I’d make sure my large items where in that room before anyone else “moved in”. 
If you are all splitting the rent and it’s evenly done, there is no “it was ours” as it sounds like this is a temporary situation where you were offered to cover the rent but are also allowing others to move in and pay too. If that’s the case, whoever is paying will need to come up with what is fist room-wise, this would make sense to include how many are in each room and or needs, so you’ll clearly need to announce you’re expecting in this case.
I know I made a lot of assumptions in this reply, just going based off what was not included in your first post, so feel free to let us know the pertinent details of what’s going on and we may have other opinions. Either way, this really needs to be cleared up ASAP, moving is stressful enough (as is pregnancy ) without having to fight for space too.
Good luck!

Answer

When you say that the house was "left to you", I'm assuming that someone passed away and left your partner the home in their will. If that's the case, then the house is his.
If not, it's everyone's to fight over.

Answer

If he won't speak up then you need to!
