Hello, I’m fairly new here, and I want to get this off my chest. My(24f) boyfriend(24m) moved in to a new place recently. His sister(20f) helped him move out. And she decided to sleep over at his place since the move got way too late (around 22:00), but her place is near there (around 10mins). I can’t help him move because his place is far from mine (around 3 hrs travel time by car), and I have work to go to tomorrow (which is near my place). I was okay at first, since they’re the type of siblings who always have their sleepovers together even as adults. But here’s where it gets weird, when I called in the morning, he tried to hide it, but he’s only wearing boxers, and his sister is only wearing undies and shirt (with no bra). I asked him about it, and said that they were comfortable with sleeping like that. Now, this isn’t the first time I saw them sleeping on a small bed together, but they were wearing clothes the last time. Am I weird to be thinking badly of them? I felt betrayed and disgusted and disrespected all at once. I really have no place to vent out to.
