I (21M) have nowhere to go for the summer: Wondering if anyone has been in a similar situation?

Context:

Earlier this year I blocked my father and deleted his number after years of emotional abuse that have continued into my college years, and especially blew up in the past two or three years. I was at home during 2024 when I took a gap semester, and blew up multiple times at him and my mom, and, like always, I had to relieve the tension in the house somehow, or find a way to get him to stop coming to my room to see if things were suddenly "cool" between us and if I had calmed down. I did this by begrudgingly semi-apologizing, or saying things were alright, knowing I'd be back at school in a few months and could be rid of the issue for a while. When I got to school finally, he kept texting me about random stuff and I didn't respond to any of it. He eventually sent a longer text, something like (I don't have the receipts anymore, but this was a common enough occurrence that I can probably recite exactly what he said): "Here's the last text you sent me: 'I'm not sure, I'll have to look into it [or whatever I last texted him].' You haven't responded to anything else. I thought we were cool. Did I do something? Did I say something? I don't know what I did. Let me know." After I read that, I blocked him, and ever since that happened in February my thought has been: I'm not communicating with him or getting near him in any fashion, and will do whatever it takes to make sure I don't.

Right now I'm finishing a summer program abroad, and will return to the US in a few days, where my mom (who's chill enough, for now) and my little sister (who's awesome) are gonna stay with me in a hotel for a week. My family's house is on the west coast, and that's where my dad is, but this hotel business will all happen on the east. After that, I have about a month and a half until school (also on the east) starts, during which time I don't really have a place to stay. Do folks have recommendations for where I could go on a limited budget? Thankfully, I have a lot of friends in various places in New England and the midwest, and I've talked to a few of them about couch-surfing, but I don't think that'll be enough to last the whole rest of the summer. I'm sort of in a weird position financially, in that I've never had a real job but have some disposable income from birthdays and such, and I could theoretically ask for some extra cash from my mom but I'm wanting to become financially independent as soon as I can, just pretty difficult to do that until I get my degree next spring (and even many of my friends who've graduated haven't found jobs yet and are living at home).

Any advice helps!
