Why won't my mom let me come home if I'm homeless?

I’m sure people will give plenty of reasons for why, and most of them will be quite legit reasons. My Parents were all about responsibility & discipline, and their idea of adulthood was “Get a job and GTFO when you’re 18”. They didn’t have this attitude because of anything me & my siblings did wrong, it was just how they felt in general. My Father joined the Navy during WWII when he was 17, as he got tired of doing all the work on the farm almost by himself (his words), and he never went back (however, his Father had died not long after the war was over, and his Mother couldn’t deal with the farm on her own. They did not own the land, and the land was eventually sold, so there was no longer a farm to go home to). My Mother simply had a major independent streak in her, and left home at 18 to go live by herself, since she didn’t like having her Parents tell her what to do anymore. So they both felt that when you became of age, you need to get out, one way or the other (and for good). My 2 Sisters did have unfortunate issues that warranted a need for them coming back home after leaving (getting divorced and then needing a place to live, one who had 3 children), but they were told NO WAY by my Parents to moving back home. They were able to get things straightened out & not end up homeless (thankfully), but it wasn’t easy for them (it certainly helped to get alimony & child support). Then I had issues with my Wife walking out on me & our 2 small children, that ended up with me getting divorced, but having custody of our kids (long story). Eventually things became bad enough that we did become homeless, or at least I did, as my one Sister offered to take my kids in, but not me with them. This happenned during the Summer, so while they were OK, I had nowhere to go. I had asked my Parents if I could just sleep and shower at home, not actually live there (as I had 2 jobs), but they really weren’t interested in my plight (“Why is it our problem you can’t find a place to live”?). So I slept in my car that they let me park in their driveway, and I was able to shower there, but then a different situation happenned: My kids needed to go to school. The problem was, was that my Sister tried to register them to go to her school district, but they wouldn’t let her because I did not live under the same roof as they did. They didn’t understand the reason why, and so she was denied, not to mention that it was their rules. So I went to the school that they had attended before, and explained my situation to the district regulators at the main office. They didn’t understand what was going on either, especially the living conditions. They didn’t offer me any help with the living situation in that regards, but they said if I could convince my Parents to allow us to be under one roof, and submit proof that we all were living there, they would allow them back into school. This was a major uphill battle, because my Parents were dead set against letting me & my kids stay with them, especially my Mother (“Fuck you, fuck your kids, fuck the school district! You get the point?). My siblings were not in my corner either, and they also argued against me moving back home, yet not offering to help either (except my one Sister like she did) making it not very fun in the least. So I was able to convince my Father to let us live with him & my Mother, but his rules were very clear: Do not interfere with anything going on or make things a problem for him, and do not bring anything with us that wasn’t absolutely necessary. He was not going to make any allowances for us or would do anything for us, it was all on me to figure that stuff out, he wasn’t gonna lift a finger. And so began 3 years of total Hell for me & my 2 kids (my Mother made sure of it), but it was better than having us separated, the kids being taken away from me, and me going to jail or whatever else might have happenned. People always talk about there being help for people in my situation, but what they don’t realize (or even care) about, is that it’s for WOMEN, not Men who are having problems. Men can go die in the streets, and no one will care in the least…
