UPDATE: My [30m] boyfriend's mother is dying so he basically dumped me [28f]

Link to my previous post the backstory
So after he breaks it to me that he doesn't want me in his life after his mom dies, I gave him some space for a few days. And after a few days he did get back in touch with me. It was a little distant, but basically like nothing had changed. He went down to see his mom and spoiler! She's still alive, at least as far as I know. Granted, her health isn't great, but she's still with us.
He gets back and continues to engage with me as if we are together, although it feels distant. He's been having some health problems and claims to be in so much pain that he's not able to talk or text me very much. His health issues are not new- a few months ago he claims he was diagnosed with an ulcer. But then every time I communicated with him, he kept hinting that he may have a more serious problem. This turns into suggesting that he thinks he has stomach cancer. I know him to be a bit of a hypochondriac but I know that he's really not feeling well so I leave him alone when he asks me too, and offer to help take care of him. He refuses my help, although he thanks me for my willingness to be there for him.
The other thing that keeps me from feeling too worried about him was that he has been milking the "cancer" angle for a while. Earlier in the year he was losing a lot of weight and was worried he had cancer- turns out he did not. Then his ex got cancer and manipulated him into helping him take care of her as she underwent a surgical procedure. I was uncomfortable with that situation but I felt like it would be selfish and petty to be anything but supportive. Then later this summer he claims his sister-in-law (with whom he is very close) also has Hodgkin's stage 4 and demands that I leave him alone all night (which I did.) So when his feeling crummy escalates from ulcer to stomach cancer, I'm privately a little skeptical but I offered up my support. And regardless of what it is, I've been VERY worried about him.
So after he finishes summer school, I was hoping that we'd be able to spend some time together. He claims that he's still in too much pain to call, text, or come visit. But on Wednesday he lets me know that he's going camping. I was frustrated by this because he claimed to not have time to see me for six weeks, but he was able to make time to go camping. He claims that it's a networking thing, and that he will be uncomfortable and in pain every minute, but he just HAS to go. He then asks if he can stop by on Monday. But Monday doesn't work for me- I work on the weekdays and wouldn't get to spend any time with him.
I tell him that Mondays aren't such a good fit for me and ask if he can make time for me on the weekend, because I don't feel close to him anymore and I want to spend time reconnecting and spending actual time together. He says he can't because he's going out of town, and then started to guilt trip me about "what he's up against," and tells me that he might not even be able to see me on Monday because depending on how his tests go, he might start chemotherapy for Hodgkin's lymphoma. So now "stomach cancer" has morphed into straight up Hodgkin's lymphoma- NONE of which has been actually substantiated by an actual diagnosis. I back down.
Later I text him to apologize and tell him I didn't realize how tight his schedule was. He texts me back "I f#cking hate you right now."
So naturally I didn't respond to this. Later on he tells me that he needs me to "not be in his life for a few weeks" while he "figures out his health stuff." I tell him that the feeling is mutual, and that being sick is not an excuse to be mean to me, and that wanting a voice in the relationship doesn't make me selfish. I also told him that "if apologizing to you makes you irate, then you need to leave me alone."
He responds by saying "I will leave you alone forever. Goodbye, ApartPersonality. I won't block you but please don't contact me." I have not heard from him since, and I have not tried to contact him. And I'm ok with that.
I feel lonely but I also feel so much less stressed out. I'm not even upset this time. I didn't realize how much the fake emergencies, guilt-tripping, cold-shouldering, and just all around unpleasantness had been weighing on me until it was gone. I'm starting to suspect that this dude has actually mental problems. I highly doubt he actually has cancer- it's just another pretense to gain emotional control, create a false sense of urgency, and use it to subject everyone else's needs to his.
None of my other relationships have been this dramatic and chaotic. I think he secretly LOVES drama and creating it makes him feel wanted. I think I've finally gotten to a point where I can move on with my life.
TLDR: Dude is actually probably crazy, tried to use cancer to manipulate me, now I'm out.
Edit: Added flare.
