How fast do people fall for you? [I Need Advice]

Speaking strictly in the past tense, I did go on one date with one guy who fell in love with me while ON the date...and said he hadn't felt that way about anyone since he met his deceased wife in high school. For me, that's a giant red flag.

Instant attraction is definitely a thing...but anyone trying to tell they are in love with you before they know you really well is full of sh!t.
