Search Results: shy and quiet girls

Me and this guy are friendly with each other, but don't know each other well. We see each other once a week, during the week he's quiet, but in person he initiates conversations and shows interest: compliments me, asks about me and shares things about himself, laughs at my jokes, hangs around me when it's not necessary, got me an Uber etc. I texted him briefly here and there, he responded, but didn't ask me out or anything.

After we started hanging out he started behaving differently around me, the way he never did before. He was ignoring me completely while talking to everyone else, didn't look at me even once, but later we talked for couple of hours one on one. I figured maybe he's nervous bc he likes me, and he's afraid of rejection and waiting for more signs from me. He even made a comment/hint about liking when a girl makes the first move.

He's also a bad texter. He's on WhatsApp only once in a few hrs for just one second and his responses are one word (also in group chats). But I sort of asked him out through text, invited him to go to a party with me. He didn't answer and now I'm debating if I had to do it. Maybe I misinterpreted him and now I feel terrible for being intrusive bc I thought he needed it and he didn't.

Why would a guy show interest but not text or initiate anything? Is he shy or unsure? Does he really only want to be friends?
