Basically my brother is ruining my life. I finally am fully vaccinated since about a week ago. I am close friends with three girls and one of them is in Hawaii, so we were waiting to have our sleepover when she gets back. After much planning we decided to do the 5th to the 6th. All of the girls in my group have little brother who are also best friends. I was looking through my brother’s messages (playfully, he knew I was and wasn’t mad about it) and I see the group chat of the boys. One of them is saying, I am so exited for the sleepover! My brother responded with, wait what sleepover? Then one of the boys said, we are having a sleepover the on the fifth. Prob at y/ns house. (The same house we are having ours at) the thing is my brother then said they had been planning this for months, which was obviously a lie. Ik I should just be happy for him, but I feel like I am getting taken advantage of. Whenever the boys are there they always ruin it. This was supposed to be a girls night. The worst part is, I wasn’t allowed to have a sleepover until I was fully vaccinated, and all the boys are to young to be vaccinated. I don’t know if my parents will even let my brother, but if they don’t then the other two boys will have a sleepover without him. Then I switch from jealous sister to overprotective sister. The boys would be leaving my brother out! I don’t know if the sleepover is supposed to be inside or outside, but my brother is definitely not allowed to do inside. I am completely fine with them having a OUTDOOR sleepover any other night, but the 5th to the 6th is MY night. This is the one thing I have been waiting for since the pandemic started. My friend is still in Hawaii and I texted her and my other friend asking if this was true, if I was the only one that didn’t know. They haven’t responded yet. (Not like ignoring me, they just haven’t seen it yet). I love my friends and I know they will be on my side, but still. Sorry for this long story, I just needed to vent.Should I be supportive? Or should I make sure we get this day to ourselves?
