Never beg someone to love or be with you, because when you do, you give them the power to use and walk all over you. When someone truly loves you, their actions will show and prove it to you, and you will never have to convince or beg them to love or be with you.
True love is eternal, infinite, and always like itself. It is equal and pure, without violent demonstrations: it is seen with white hairs and is always young in the heart. - Honore de Balzac
There's nothing quite so humbling as thinking you're completely over someone, then realizing you're not even close.
