Guy's Behavior

The guy I like basically told me likes me around a week ago, but recently he's been acting distant. Is there a reason?

Alright so the guy I like said things like "is it not obvious I like you lol" and "I'd consider loving you one day" to me around a week ago, but recently he's been replying slower (from like a few minutes to 2 hours) and seems like he's acting distant. Just last night I asked him if he thinks he likes me (to confirm he still has feelings) and he replied "I'm not sure how you want me to answer that lol". He then replied with "I think you're cute." When I brought up how he said he'd consider loving me one day, he called me delusional and said I needed sleep (it was very late). I then send him the screenshot where he said it and he put emphasis on "consider loving" and how he needs to stop loving someone else first. When I asked if it was an ex (he told me about all his exes), he said "not gonna answer". He's told me all about his life, exes, and TMI things, I just don't understand why he's acting distant and not answering a lot of questions recently. I could care less if it's an ex and we're not even dating, so he should be able to say it's an ex from a friend's perspective. Am I overthinking? Has he found another girl? Is he just going through something? Maybe just not confrontational? I see him playing games all day (I guess it's kinda his job) so I don't know if it's cause he's "busy"... ahhh I'm driving myself insane please let me know any insight thank you~

Edit: Call me cringe but I met him online and we have NOT met in person yet~ we both have active social lives online and like to play video games so we have that in common
