Am I childish or is what I’m feeling valid?

So my husbands family always comes to us when they fall on hard times hard times..meaning his sister is always homeless and trying to move In or expects my husband to fix whatever she’s going through

But the problem is their mom stays with his sister as well so it’s his sister their mom her 4 children and we live in a 3 bed room.We have children already and over where we live our land lords come out every week.

That’s part of the problem the other issue is the way they treat me I told him no because this is not the first time,he even said no but took back what he said because he refuses to let his mom go into a shelter but she’s the reason she has no one to go to they are rude and disrespectful to the people who let them stay.

What I’m trying to get at is when I said no to all of them his sister says she was going to beat my ass and her and the mom got upset even her boyfriend threatened me and he’s part of the reason she’s in this mess he said my husband needs to control me and let his mom in law move in and that my husband is a no good as person for letting his mom go homeless mean while he played video games and didn’t even help my husbands sister pay bills

My husband still let his mom come but not his sister but I don’t feel she needs to be here to because they always mange to come back some how,they is his sister and her children because the mom is the baby sitter while the sister works it’ll turn into can the children stay the night then, can they stay another then a night will turn into weeks, weeks to months then we’re back at square one with them again living here destroying things.

He says I’m being childish by not speaking to his mom but why would I when one I told you I didn’t want her here two they caused a scene and said they were going to cause physical harm to me I recently found out they never even liked me only been faking due to one of his family members blurting it out because they were bad at his mom but they didn’t express it until recently so I just stepped back from talking to them ever since never been rude I just stay in my bubble they say all types of hurtful things and that we found out but they act clueless as to why I’m not speaking then pressure me into speaking to them pretend as if they didn’t say anything

With my husband I feel he tells everyone what they wanna hear thinking it’ll keep the peace and it actually makes it worse he tell me one thing like oh she’s here until one day but then tell them another and when I’m expecting her to be gone and I get irritated by it he’ll switch up what he told me then I look like I’m just in the wrong for being mad because I expected them to be gone by a certain date

Am I being childish and doing the most for not speaking until she leaves I just have nothing to say I’m really disappointed in him I feel we should have to adjust our place for them
