英文翻译，高手come on ！！！

Once I loved you so much. I have been dedicated to you. I treated you with my whole heart and soul. Enough I have done for you. I didn't do you wrong. But how about you? You cared about nothing, and regarded our love as something easy to destruct and throw away. I'm not your toy at your complete disposal. My understanding and tolerance for you were only mistaken as your excuse for betraying me! Now that leaving is your choice, don't come back then, never. I have run out of my patience. Let's stop our contact. I'll forget you, and please forget me, too. Wish you happy and merry. Goodbye!

I was so into you, and giving you whatever I can. I have been treating you so well, so sweet and doing my best for you. But you? you care about nothing, taking our relationship fragile and destroyable. I am not your pet, that you can summon and dump for fun. My patience and forgiveness is again and again taken as your wager of betrayal! Now you decide to leave, for good I wish. This is beyond my last forgiveness. I hope our connection ends here for good. You are now walking out of my life forever, and I will be walking out of your memory too. I wish you happiness. Goodbye!

我根据你要表达的内容稍微调整一下，有点口语化．．希望有所帮助．．．．．不需要这么绝吧，分手亦是朋友．．
