You can't make someone love you. If the one you love can't return the love, get a clue and move on with your life. Your heart is going to end up in the Heartbreak Hotel or the Y-Tell Motel. You're not responsible for someone elses immaturity, addictions, temper, lack of faith, low self-esteem or inner turmoil.
All relationships have thorns but the rose is what makes it beautiful to behold.
The rose makes it easier to endure the thorns in life. If the rose is gone and only the thorns remain, it's time to revaluate your life. Love should not need convincing. Love should not be a battle. Love should not have you sitting by the phone waiting, waiting, waiting.
