mad 😡

Ok so my girl cousin asked if we would let her make her moms birthday party at my place since our place is pretty big and there place is much smaller and the moms place she would just be cleaning instead of enjoying the party. I said I don't think that's a good idea since my brother had also asked and my husband said no bcs he didn't feel comfortable with him inviting ppl to our home we don't know. And i didn't want my brother to get butt hurt bcs if we let them and didn't let him. But she then said it wouldn't be a lot of ppl just family.
So I was already thinking of telling my cousin no since I had just had my daughters party and I was super stressed I'm now 34 weeks pregnant I pretty much did everything on my own from cooking putting up decorations everything my husband didn't really help. we ended up doing the party outdoor since we had just gotten our rug cleaned and didn't want ppl going in and out the house. But they still did no one was really watching there kids I was trying to attend to my company and trying to keep the kids out the house while my husband just sat there not helping so I told him no I didn't want to be stressed out all over again and him not help out. And having me to deal with kids running in and out the house or going into stuff. So he had agreed and said ok. He also wasn't comfortable with having ppl over we don't know like there side of there family and friends. So I told my cousin I would talk & give them an answer. So later that day I explained to her what me and my husband had talked about and we had decided no. So the next day when my husband comes home he tells me he ended up telling them
Yes. I was furious we had just talked about it the night before and had agreed. so my cousin and her husband went behind my back and asked my husband after I had already told her what me him had decided. We'll turn out my husband agreed on letting them after all they said they would pay him 400. I don't care about the money I take care of my home and other ppl don't. I'm so pissed that he would go against what we talked about and went behind my back and changed his mind with out letting me know. I'm really upset bcs now he's making it seem like it was just me that didn't want to let them in the first place. So he's made it seen like my opinion doesn't count. And it's my home too so I have a say. I just can't believe it and then he had the nerve to call me selfish and that I was going to regret being that way. I don't understand why he would do that I'm furious. Am I over reacting or is he in the wrong for this? I know for sure me and my cousin won't be on great terms after this that's for sure causing all this when they can just do it in there own place and causing problems between me and my husband. I'm more upset at my husband for   Making a decision I'm not ok with.Â
