I've got two younger sisters. The older of the two is severely autistic to the point where she is completely nonverbal and the state considers her mentally to be a 3 year old. She's regressed in a lot of ways after being confined at home during the pandemic, causing her to have very frustrating behaviors. Even though I help her out of obligation, I have become so burnt out from dealing with her that I got a part time job just to stay away from her even though the government gives us free money to handle her. To me, this sister is nothing more than a very high maintenance pet that I'm forced to care about. That sounds pretty hurtful I know but it's not like she can get offended by it.
My other sister and I are/were pretty close to the point where we're definitely friends. Having to grow up with people like our shitty father and now our less shitty but still frustrating mother tends to bring people closer together. I say we were pretty close because I hate my sister's current boyfriend. He's got absolutely no spine to the point where after six months he's still too scared to meet me. I mean come on, I'm not her goddamn father so stop acting like you have to be scared of me like I am. Most of the dudes she's dated are weak and pathetic like this except for one who was pretty cool but this current guy is the worst and that's saying something since one of the previous ones was someone who would literally sniff and try to eat her hair…in public. A few months ago I yelled at her and made her cry because I made it clear how little I care for her current boyfriend and it got so bad she stayed at a friend's house for a few days. I know this makes me the asshole which is why I'm shocked my sister now tries to have her cake and eat it too by trying to be friendly towards me while still going out with him. I'm okay now as long as she doesn't talk about him because one day I hope they can break it off likes she's broken the hearts of so many other loser dudes.
