<human>: We've known each other for about 6 months now but in the past month we've been talking a lot. We chat all day at work, sometimes for an hour or more at a time (and we work at a tech startup so it's not like we should be doing that in the first place). Then we chat for hours more in the evening when we're at home. If it were anyone else but this guy, I would be 100% certain he liked me. We stay up till 1-3am talking and he's constantly messaging me first about random stuff. We tease each other all the time and he'll also compliment me a lot. He notices if my behaviour off and what I wear. 

So the other day, when we were chatting online, it was revealed that he had never liked a girl before and that all his relationships had been with girls who had asked him out and he agreed to try it out. And that he had become "quite fond" of them during the relationships. 

I knew his feelings and emotions weren't very strong but that's just... Sad. And a little disturbing. Considering how attached I've gotten and that he basically told me he felt nothing towards me. After I found out, I basically ignored him yesterday and only talked to him when he started and didn't try and continue the conversation. He asked why I seemed quiet. How can he be perceptive enough to see that but not that I like him? He's had many many many girls like him but he's always been too oblivious to realize.

Give me a shortened version of the text
<bot>: So basically what I want is other people to confirm that if an autistic person tells you they've never liked a girl or had real feelings before, that I should take their word for it and give up any hope.
