Can a guy still be in love with a girl four years later after never seeing her before?

The term 'in love' is somewhat common to the term 'puppy love or crush'. Although it is possible that a person still have their emotions for someone even after a long duration of time. But this applies as an exception since there are factors that contrasts this fantasy. If the guy confesses to the girl of his feelings, the girl still needs to be skeptical. There are many liars and players nowadays and girls need to have more security for that. But if the girl trusts the guy and believe that he is trustworthy and never had a record of betraying anyone, its her choice to accept the person.
