The asker hasn't said it was a break up instead of an unrequited love.
@JohnDoe3000 The unfair thing to do is to use the next guy to get over the previous break up/unrequited love, because she will only be a rebound for the next guy and he may leave their relationship being hurt.
I meant that the guide you linked to wouldn't necessarily apply in the case of an unrequited love. by the way, people have rebounds because they actually work (with a rebound it takes you a month to get where you'd be after a year of "being active and having fun with your friends", when it comes to forgetting about someone), but yeah, don't go promising them your eternal undying love when it's just a rebound, probably better to have a friends with benefits.
