it is a state of mind , so the guy imagines his perfect girl behind the screen, and start to fall in love with this imaginary picture...the illusion will increase until he really fells in the webs of love.
and even if he see her for real, he will accept her faults in reality.
as i said...love is a state of mind...so why not?
seeing ...talking ...dealing...facing problems are only factors in helping to create this state of mind.
