Do you hate your Ex?

Alot of times i always see people say they can't stand their Ex or they even hate them, its hard for me to believe that because at one point they were your bf/gf and you had feelings for them. I understand things happen and not all relationships end well but i couldn't see myself hating someone that i once loved. Till this day i still pray for my Ex i always wish them the best and hope they're doing ok we may not talk or keep in touch but I'll never regret dating them or i couldn't wish anything bad on them.
