Is NOBODY wrong in the post ? POST : I [18F] am starting to get tired of my older sister’s [F21] boyfriend coming over on very short notice. He will just text her that he’s on his way, or show up unannounced. Often times it’s after work or late at night, so I have long since rubbed my makeup off and gotten pjs on. He will sometimes stay all the way up to midnight and I feel like I need to hide in my room if I am not decent enough. 

Some background about the situation: My older sister and I have been very close our whole lives.  Growing up I never felt like I NEEDED friends because I would just go home and play with my older sister. Now that she has a boyfriend, I tend to feel jealous but I try to hide this to the best of my ability. I have gone out of my way to make friends with her boyfriend so that the 3 of us can hang out. He’s a cool guy, and I’d consider him my friend. Nonetheless I always feel hurt that she prioritizes him over me. I know that’s normal, but it hurts. We really don’t spend as much time together, and it seems like she’s changing as a person too quickly for me to bear.

Tonight in particular hurt. My sister got off of work at 6pm from her first day at a new job, and I was very glad to see her. I was feeling nauseated and wanted to lay down upstairs for a bit until the feeling went away. I was already anticipating what we could do together later that night.

Just a couple minutes later she comes upstairs and asks me “Hey, can my boyfriend come over?” I’m surprised, and begin to protest, especially because I am feeling so low and don’t want her boyfriend to see me in this state. I express my concerns and feelings to her, but it doesn’t matter, because she just tells me “he’s already on his way.” 

I told her that I would prefer that we spent some time together, but then she uses the excuse that she has a lot of homework to do. She told me that she’d just talk to him for a little while and then ask him to leave so she can do her homework. Fast forward to 3 hours later and I still here them laughing and him playing guitar and singing downstairs. I am currently hiding upstairs still, trying not to lose my dinner, and I’m wondering if my sister lied to me in order for me to say yes. I’m angry and lonely and I wish that she wouldn’t use the homework excuse to not hang out with me, but then proceed to hang out with her boyfriend for 3 hours. 

My older sister is drifting away from my family and seems to try and get out of the house with any excuse she can. It’s mostly due to tension between her and my parents, but I feel like it is starting to include me too. I am afraid that if I confront her she will move out and never look back. I just try to not rock the boat in hopes that we can keep our relationship.

So reddit, please answer me: AITA for having these feelings? I feel like I might be a bit immature. Please give me advice on what to do next that won’t destroy our relationship. I don’t want to lose my best friend!
