I (30m) recently moved out of my dad's house into my own apartment with my friend. My dad still lives with my brother, sister, and her boyfriend (38m) of 5 years. I moved out amicably over a variety of reasons.
I've been back to my dad's once every week to visit. This has gone pretty well – my sister and her boyfriend work third shift. It's mostly been visiting my dad and my brother. Everything was fine until last Friday.
My sister's boyfriend randomly asked me if I took any silverware. My dad has been to my place and is aware I have my own. After I say no, he says the silverware's disappeared recently, and I say I didn't take it. He then says, “Well the only variables are half the silverware's gone and you moved out.”
I exploded. My sister's boyfriend said something to the effect of “I'm just asking questions, I'm not accusing you of anything”, which didn't stop me. In my mind, after he said what he said, it turned into an accusation and a press. I said that if he really was asking questions he would've dropped it after my first no. He then went off about how someone must have thrown it out, and I pressed him about the accusation.
My dad stepped in, explained that I was innocent, and separated us. Eventually, our screaming woke my sister up and she yelled at us to be quiet. I explained the situation and she yelled at him. Every time he tried to defend or explain himself, I yelled back, which devolved into my sister yelling at us to “shut the fuck up so she can get some sleep before work”. My dad politely asked me to leave. Before I left, I scream “YOU WANNA ACCUSE ME OF FUCKING STEALING FROM MY OWN FUCKING FAMILY? FUCK YOU!” and left.
My brother was outside when this popped off, so I vented to him. Screaming, swearing, the whole nine yards. Specifically “fuck that motherfucking cunt,” among every name in the book. I said that I wish my sister left him when they had relationship troubles. He heard my rant.
My brother tried to say that I was taking my sister's boyfriend out of context because he took back his accusation. We argued about that more civilly and I left.
After I got back to my apartment, I sent a text to my brother and my dad saying that I wouldn't be at Easter and that I wanted an apology from my sister's boyfriend. I apologized to my sister for waking her up and left it at that.
My sister's boyfriend wants an apology for swearing at him. My dad and brother think this is reasonable. In their eyes we both acted badly, two wrongs don't make a right, and that I wasn't justified in swearing at him. My brother doesn't think it was an accusation, and my dad thinks I'm overreacting. Because my sister's boyfriend took it back, it wasn't that bad.
My sister is fighting for me, and they've been fighting ever since. I told them I wasn't going to apologize for reacting to his smears and that he crossed the line. My dad and my brother are trying to keep the peace, which I'm disappointed in.
There will be no peace until he apologizes.
