In-Law Vacation turned nightmare

First timer, here goes. I have a history of avoiding family vacations bc I grew up in an abusive family. I like to have an “out” in case. Been w boyfriend for 3 yrs, he knows my history. I’m in therapy, and working on being more open to family (not mine) events. On island now and my fears have been realized. Took long trip with boyfriend earlier this year and it was good.

Night before flight, 2 hours sleep bc he wanted to stay at parents house instead of driving down the morning of. On flight here, when a lady offered to switch so we could sit together (he would have gone from opposite aisle to window), he said, “why would I do that?” She was surprised (as was I). Five hour flight, middle seat, broken tv, no leaning back (in front of exit row).

First night, i go to bed early bc I’m working on 2 hours’ sleep. Brother of bf says to me, “too bad, I’m watching the game (tv is in the adjoining room to the one we got assigned - we all went in, but somehow we were the only couple who didn’t get a say in the rooms). Next morning, am woken early bc adjoining room has no sound barrier to main space and in law parents are up before 5 am.

I ask what can we do so I can get sleep. Brother offers to switch rooms (turns out, he didn’t like the one he picked). I profusely thanked them. It’s in adjoining bungalow w thatched roof. I take a nap in there and it’s got mold (roof). I have asthma. I’m the only one with a sensitivity so no one could have known until I spent time in there. I tell family rather than make anyone switch with me again, I’ll just use a sofa.

Second night (but 3rd with only a couple hours’ sleep), I make up the only available sofa (bro used the one the adjoining room for his baby where the other sofa was). Mom comes in from her bedroom, sits down, and says, “I’m not ready to go to bed yet.” Bro sits down with her. (It is no secret I’ve had no sleep for two nights). They tell me I can stay up and wait for them to go to bed. They gave me a look - it was a moment. I pick up my bed stuffs, and sleep on the patio furniture outside. I got about 3 hours. Next morning, I tell my bf (who slept in mold room bc he doesn’t have sensitivity) that I’ve found a flight to leave early and what went down. He goes and intervenes with family while I’m in bathroom (I had specifically asked him not to bc the moment wasn’t an accident). I sleep for an hour on the other patio floor and by the time I wake, the flight is gone. I have to wait a day minimum. Mom and dad switch rooms with us. After his mom and bro give varying accounts, Bf doesn’t believe my story until dad confirms it happened bc he’d been in the room at the time (I didn’t even realize he was there bc it was such an appalling moment). Family now tells him he should break up with me - it is tense. He thinks I’m overreacting. This is not a vacation.

Sorry for the length of the post.
