You made me feel just like the rest of them did. Completely worthless and undeserving. I truly thought you were different and would never hurt me like that! I guess that I thought wrong. It's not the only time I've thought wrong. Oh well.
Its never a problem, unless you are involved with a sociopathic narcissist. In that relationship, giving freely of yourself leaves you empty and wondering how you got so hurt. Give your life freely to those that deserve it, not demand it.
