what are your thoughts on this???

idk maybe i’m overthinking, but i get really insecure when my sister & bf hangout, or when they’re alone together. i’ve just had history of people (guys specifically) who’s meant a lot to me, choose my sister in the end. i’ve lost two friends this year that i’ve considered really close friends, one of them is her bf but whatever. anywho, i get insecure. and last night i was away babysitting & my sister & bf were home alone. my bf knows i’m insecure about her & even tho we were fighting he told me he’d kick her out of our room if she was in there (we got a new cat, so she was keeping it in our room to stay away from her cat) but he didn’t. she sent me snaps & i could clearly tell she was in my room w my bf.

i don’t think they’d do anything but this is what’s bothering me.. my little black blanket i has smells like mad tide air freshener. the one we keep in the bathroom, & it’s pretty clear someone sprayed it. idk if they fucked or something in my room & covered the smell or something but it’s been throwing me off. i’m sure they wouldn’t just spray my blanket if the cat peed on it. fuck i’m so confused & overthinking. but what do you guys think?

edit: we all live in the same house. me & my bf in our room, & my sister has her own room.
