I need opinions. Please help.

Okay, Hi. So, do you ladies believe in liking someone you barely know? I mean, i know this guy. We text maybe once a week or twice if i'm lucky. But our jobs are right next to each other so we see one another often. He recently bought me lunch without me even asking or anything. He always seems so excited to see me.. Part of me feels like i'm catching feelings, or am i just crazy?
