Instant attraction vs taking time to get to know the person to date. Am I getting transformed (See description)?

I have never got attracted to anyone instantly except for one moment. But it didn't go ahead as I've only seen her on public transport. And it was only one time as well. In the past, in all the other cases, I needed more time. This instant attraction thing I mentioned was rather new to me. (this incident I mentioned was just two days ago actually). What do you think? Am I'm getting changed?
