Broken: when something cannot go back to its original form completely
Bent: when something is out of shape yet can retain its full form
Someone who's heart is broken, they do not ever retain their hope in the thing called love. If their heart is truly broken then they cannot be helped. So therefor, do not ever say that someone has broken your heart. They have only bruised it. They shall not ever feel like they cannot trust anyone so thou shall help the bent be back to full form.
You do not know broken until you have placed someone there yourself. I have saw someone whom I claimed to love, change their entire existence. They stopped what they loved. They had stopped caring for anyone. They cannot go back to who they were because I was their last chance of happiness and I ruined it. I have learned that I severely need them in my life because I am not complete without them. That is what love truly is. I had fallen in love with them, my brain didn't think I had yet my heart knew otherwise. I turn their life upside down. I cannot love myself since I had done that. You will never stop loving someone. Part of you will ache for that person, for the rest of your life. I do love others. I love the one I am with. I will always love the one I had broken. Sometimes broken things can be fixed even if they don't go back to normal. It is always worth a shot.
