Rebound

Rebound
when u break up with someone, it's very hard to get over them.
do we really need a rebound person to fill in that hole in our lives?
or can we just have many friends to help us forget the other person?

can we just, just maybe be alone and not rely on people?
do we have to have sex with the Rebound person in order to make us feel better?
what is it really about having a rebound mean?
