(someone who enjoys pain, or who derives pleasure from harming oneself or being harmed by others)

You found someone who makes you feel wanted,needed and appreciated its been 2 years but I'm still asking why? why ?am I enjoying the pain? how to unlove the person I love the most.. am I wasting my time, emotions,energy etc with the wrong person but in the end of everything I will love you even if it hurts.. and it will never change Clr.
