Can't people just leave me alone?

i'm not the only autistic person in my bf's family but I'm the least apologetic about it. i guess not everyone sees that as me protecting my sanity but how rude I cannot let them get their way.

i was meant to take the bus back to my city last night after spending easter sunday with my bf and his family. Not only did it not show up, no one picked up the phone when I tried to get a ride back to their place. it was cold, dark and I didn't know the city. I called four different people at the party until someone picked up so I was already upset about the whole thing. I had time to calm down before my bf arrived and on the way back I said I'm not blaming him for not picking up the phone as he was with family and all that but the whole thing made me upset to experience it and wait for an hour for a bus that never arrived.

I hate sleeping over anywhere btw. his childhood bed is a twin and we're both over six feet tall so he slept on the air mattress. we both snore. he loves waking me up when I do and I don't. I woke up five different times so safe to say I slept like shit.

Now about this morning; they love to do a big family breakfast at the table and start conversations. I don't. I didn't say anything more than morning and started getting myself something to eat. I refused coffee because it fucks with my stomache and also I have ADHD so caffeine works differently for me (no one ever remembers that). I sat down and started eating, staring off into space, then my bf's mom comes in the room and offers me coffee. i again politely decline. THAT is when his dad asks "do you not drink coffee?" I am already pissed about not getting at least an hour alone to wake up plus the lack of sleep so I just say I don't want one right now. then he asks again the same fucking question so I repeat my answer, and one more time after that. I tell him I don't always have some. as if he wasn't rude enough already he asks says "it's not hard to answer a simple question". this honestly was such a typical old man response I fucking swear. I reply "I prefer not to." he says AGAIN "it's not hard to answer a simple question" to which I say again "I prefer not to.".

I finish my meal and go back to the bedroom to regulate. then my bf comes in to say that everyone is saying I snapped at his dad. i fucking did not. i hate allistics I hate allistics I hate em

I explained to him how his dad kept asking me about bullshit and that I answered politely and with a neutral tone. still won't accept it and somehow I'm the bad guy here.

can't wait to get home ffs
