How do you ask a guy what he wants in a normal human way?

I am very socially awkward and have aspergers, so has this guy I reunited with after having dated and he nowadays sends very different signals from having been overwhelmingly into me before but I also did kinda break his heart when I didnt want him but I was just confused and now we're talking again but very little.
He told me he's seeing someone 2 months ago and that he doesnt know if its gonna get serious or anything but he only wanna date 1 woman at the same time but its likely it didnt work because he's never had luck with the ladies and it says hes still single. He never text me nowaday but he likes posts on my page and such, and when he do talk he says lowkey flirty things like he's dreamt of me. He keeps it very casual the rest of the time tho.
Tonight I asked him if he's been celebrating easter and he said a little bit, then I asked him if he celebrated WITH someone and he said that yeah his parents are visiting. He also said this on valentines day!!! But its not impossible because hes very close with his family and they often visit him and him them. And then he very quickly said he's sleepy but I replied that I thought maybe he had "somebody else" over... He didn't answer that just logged off and went to bed.
I dont get him at all. My friend thinks im lame for not asking him what he wants and if he's still dating someone or 100% single especially when he likes my posts and stuff, texts me randomly sometimes and such but wont make it clear what he feels. I've just avoided it because I dont know whats okay to ask people about their private lives + im afraid of causing trouble!!! I dont know what I want myself! I only know that I dream about him every night and want to things to be how they were when we dated and that its kinda sad if id lose him to someone else and him never knowing that I liked him or anything. So please tell me how to ask in a normal way what someones intensions are thanks.
