It won't always hurt ... I hope

Dear FutureMe, I'm writing to you because I need somebody to listen to me without judging me ... You will, of course, have already judged me by the time you receive this, therefore you won't have to judge me while you are reading this. ... Even if you do judge me, at least I know you will keep my secret. Right now it hurts a little too much to tell anyone else. My boyfriend, your ex-boyfriend, has just broken up with me. He gave no valid explanation, and did not even break up with me in person -- it was through a text message that simply said "we shouldn't be together". I don't understand why he broke up with me. We were only together for a little over two months, but we had been friends for about six months before that. He was always talking about how he wanted to marry me, how he wanted to grow old with me, and how he wanted us to be able to see each other every night. He talked about how he would support me and love me. But in the end, he didn't, and I don't know what I did to make him push me away. I am so confused right now - was this his plan all along? Was he just using me? Or did I do something to hurt him so badly that he couldn't bear to be with me anymore? What did I do? I don't understand. I'm not sure who I hate more right now: myself or him. Two years have passed since he broke up with you. Have you found someone new, or ... did this breakup damage you to the point that you are no longer willing to trust anyone? I don't know if you remember, but that was how you were before you started dating him, too. You didn't want to trust anyone, ever. But then, he came into your life, and even though you were afraid, you found yourself becoming closer to him, and it got easier to trust. Right now, I think you were stupid for ever trusting. You should have known better. But you're my elder, so I have to respect your opinion. So tell me, what do you think of this situation? Is it foolish to trust?
