So this is mostly a rant, but ill be honest im angry and looking for opinions.

So long story short, my boyfriend and I (and our almost 3 year old) all shared a house with his dad, his sisters, his brother and husband, and their two kids. Everything was fine when we lived together. They all moved out so now we just live with my boyfriends dad. The two kids upstairs shared a designated playroom in the house, and we had the whole basement so none of our sons toys were upstairs. Obviously after everyone moved out, we moved his toys up too and that is now our soms playroom, and of course if his cousins come over the can play too.

So the moms of the two kids tend to go outside and smoke a lot while their kids play unattended in the house. They dont even bother checking to see what they're doing. And now that the weather is nice they stay out there for over half an hour (the kids are 4). So like I mentioned they moved out. They came over probably once a week out of nowhere (which is fine). However after they left they eouldnt even have the common courtesy to put my sons toys away, and their kids play pretty rough. Whatever though, I always cleaned up after they left and went about my day.

Last week my son was having a nap and they came over out of nowhere, like usual. My son sleeps directly under the playroom, so it gets loud (anybody who lives in a basement can probably relate). Like I said, their kids don't play nicely and tend to be super loud when playing. It also doesn't help when their moms are outside smoking. My boyfriend was angry about this and went upstairs to tell them our son was having a nap and they were being too loud. They got offended and started swearing at my boyfriend in front of their kids (normal for those two) and said theyre never coming here again.

Now, my sons birthday is on Saturday and my boyfriends dad says they arent attending, which hurts honestly. They know my son won't have any other kids at his party because of covid and I bought games, decorations, and stuff for the kids to do. This honestly pisses me off. Especially because theyre attending his other cousins birthday party today. They also know I bought all this stuff before they had an argument, and now they're taking it out on my son and his happiness.

He loves his aunts and cousins and I know he's going to be confused as to why they aren't there. He's going to be surrounded by adults on his birthday and I honestly feel bad for him. I even bought a pinata for the first time. Im so heart broken for him, but at the same time I'm so angry. I would never do that to one of their kids. Part of me doesn't want a relationship with them anymore, but I'd be hurting my son in the process doing so.

Thank you to those who read this far. I know this is long.
