Don't waste your time on someone unwilling to love you the way you deserve. Don't bend over backwards 'cause they walk away. When you miss them, remember the hurt, and when the right one comes along, don't miss your chance over someone that's already gone. Someday, some lover will show you how beautiful being loved can be. Stop looking for someone to complete you and wait for the one that makes you feel complete.
Don't waste your time on requited love because eventually, someone will come around and treat you the way you deserve to be treated.
