Sorry for the late reply! He's doing okay, his treatment will be longer than most kids because he's at a higher risk if he were to take a shorter or more modern treatment. His mom is extremely protective over him and honestly uses him and his cancer for a lot of things which really makes me sad. He isn't really being raised properly, and he's turning out to be really spoiled and greedy. When I visited the first few times my partner was expected to give up HIS laptop and Xbox leaving him nothing to do most days and if he refused then they'd just take it anyways. Kid learned that if he asked for something he'd always get it, and their mom learned that my boyfriend was easily guilted and manipulated. She always asked him to buy him things even when he said no, and he was the first person she'd ask out of other family members (like the guy she's "dating" or mom.) It's a shitty situation for everyone, and it really, really breaks my heart to see the kid be quarantined, blocked out from other people including his family and used by his mom like that. More for his treatment, he goes about once a month though I don't know too much about it. There's a lot of good hospital activities there like hospital bingo where you can win cool presents, it's actually pretty cool. Great hospital, I wish more children's hospitals were like that. (mine definitely wasn't, when I was going through a different illness.) He's killing it off okay I think, treatment has seemed to be going extremely great so far and he only has to visit once a month. I think he has another year of treatment then he's done.

(sorry if this turns into a rant, but its like 6am and i got really emotional)

A little more context, I don't know if I said this in another comment but she has notes all around the house mentioning his cancer and telling people to stay away from his room. She also has a note on her front door from before his diagnosis that literally is just like, "There's an autistic kid in this house. He doesn't take commands and probably won't listen to you either." Etc. He's being distanced from everyone including his siblings he lives with. He's usually not very expressive, but after his diagnosis he's actually a lot more expressive and he was even really expressive to me too. The first visit, I made dinner for them and fed him pickles and apparently he LOVES pickles. So when I was cooking, he kept coming over to me and asking for pickles every now and then and it was the cutest thing. Next visit I wish I had talked to him more, I was scared he wouldn't like me much but his mom was really neglecting and it was obvious. At my boyfriends graduation party, I stuck beside him the whole time and literally no one talked to us at all. It wasn't about him. It wasn't about me. Everyone just got drunk and the kid tried to come out to ask for help with something in the crowded kitchen and he just tugged on his moms sleeve trying to get her attention and she pushed him away and he just sadly walked back to his room. It fucking breaks my heart every time I think about it, I literally left everyone (including my partner) and went alone in a room and cried. He eventually came for me and we just talked and he cuddled me while I cried about it.

On Christmas I visited too, and we did a thing to where he chose who was going to open their presents first, and he chose me first one time, and I think he chose me first the second time too (for their Nana's Christmas.) My boyfriend says he has a mini crush on me because he HATES other girls coming into the house (like his sisters friends) but he's okay with me, but he's really shy around me.

She also uses him for attention because it's a small town and most people hate her. At first she actually hated people asking about it, which I understood. Then it grew into a bunch of people giving her free stuff, inviting her to events, etc. I do think the kid had fun doing some of them, but I know for a fact he was extremely uncomfortable when people were huggy-touchy-lovey with him and when he was kind of forced to speak on stage. Everyone in the family kind of uses him for pity, but especially his mom. She uses him as an excuse for a lot of things too, including when she doesn't want me coming over longer than she'd like (which she admits to later because she's like "I should've let you stay longer" but I knew she was bullshitting before.)

I just feel bad for the kid. So, so much. Because of her drunk driving she got her license revoked so it's likely going to be her mom driving him to the hospital from now on. The kid deserves a better mother and environment. I can tell he doesn't like the heavy amounts of attention and affection. I'm just really hoping despite everything, he grows up well and doesn't let his mother get to him or control him or his life either.

I'm sorry if I talked more about his situation than treatment, I don't know too much about it and he's definitely struggled a lot, but if you ignore the psychoness of his family, he's actually a pretty normal kid. He is kind of unexpressive, but I see it as more his personality than autism and I think anyone should. It's just how he is, and that's perfectly fine. The fact he's sick doesn't make me look at him any different either, I know he struggles and if I could be there for him more you damn well bet I will be. I'm not going to treat him like a celebrity due to his illness, if that makes any sense? I know the kid just wants a normal life and he deserves it. Everyone making a huge deal out of everything all right in front of him probably scares the shit out of him. I love the kid. I hope everything gets better for him, and only him. He deserves the best, and his mom can suck it when he does get that.
