I Am Heartbroken Right Now

I was a bad person in my last relationship. I did so many things that hurt my ex for revenge on what he did to me and I never stopped. I broke up with him and found myself shortly after, in another relationship. I wasnt ready but it felt so right and he pursued me like no other and said he would wait til i was ready. Maybe i wasnt ready but we ended up together. I found myself totally and completely in love with this man. I didnt even know i could love like that again. He was the best thing to me. We were making arrangments for him to move in soon. We broke up 2 saturdays ago. I gave him another chance. A few days later we had another issue but i stayed still. I was even happier than when we first got together. The kisses were better, the love was greater, the fun we had was even more fun and only for these two weeks. Last night he texted me that he had to leave bcuz of him n not bcuz of me. He left a letter with a rose and the key to my place. I didnt read the letter cuz i dont want to feel worse than i already do. I will read it when I feel alive again and strong enough to read what could be the worst thing ever idk. I feel like karma really did a huge number on me. I was so happy then we broke up then i was even happier than before when we got back together just to have my heart broken harder. I guess what im saying is, dont be a shitty person cuz what u think is ur karma, probably wasnt. This right here is brutal and if its not my karma, god help me, I cant imagine anything being worse right now. Damn....
