I heard that if a guy stares into your eyes for more than 2 seconds, then they like you? I made eye contact with this guy for about 4 seconds, that's a lot if your just looking into someone's eyes. Do you think that he MIGHT like me?

Not true at all. Staring means absolutely nothing at all so don't read so much into this. If a guy is interested in you, he will let you know when hes ready so don't believe everything you hear like this
