For clarification:
"Absence makes the heart grow fonder" - when people are apart, their love grows stronger.
"Out of sight, out of mind" - If you do not see someone or something frequently, you will forget about it.
I think the latter is especially true when someone is playing "hard to get" and you essentially just get turned off and cbf with it.
