How do You know if you like a guy?


Im 21 and I’ve never been in a relationship so idk how you’re supposed to feel.

I’ve only had one crush my whole life and it was instant attraction like I knew him from another life kind of feeling, but nothing never became of it.

I’ve yet to find anyone with the same energy connection and idk if it’s common. I met a guy a month ago and he’s crushing on me. I like him but I don’t know if I feel the same way. I have yet to feel an attraction like I did with that one guy a few years ago. Can attraction grow or am I just not attracted to him?
