Being called boring by someone so interesting

Met someone a while ago. The best way I can describe him is hes confident and a little nerdy. Either way I found him so interesting and awesome. So much so that I give him compliments when we pass each other and he takes them well. It's harmless, and the purpose of me doing that is just to hopefully make him feel good about himself.

Then we have a small chat through text a few days ago, and he calls me boring for not having a bigger social circle.

Maybe I'm stupid for thinking he thought I was cool too, but for some reason that really hurt to hear. He's not even wrong though. But for him to say that in the first ever proper convo we've ever bad when he genuinely hasnt fully gotten to know me yet really hurt me. Like I'm over here singing his praises and all he's deduced from me is that I'm boring.

I haven't said a word to him since and he's the same. Earlier today I was crying over something and he accidentally saw me. Just left without a word.

I genuinely thought he was so cool, too...
