<human>: Can you give me a shortened version of the text?

It's really true that nothing lasts forever. Even if she (F20) gives you a special hand made gift that says she will love you (M20) forever, it will end up being not true. I still carry it around with me everywhere, in my backpack. I look at it and smile because I remember all the good times we had together, and over 5 years there were many. But, then I cry because she's not in my life anymore. She was amazing and made my life amazing. But now, there's nothing at all. There's no one to talk to about this, she was the only one I could ever talked to, the only one who understood me, and now she's gone. I loved her with every fabric of my being. Maybe it's pathetic, but over 4 months later, I still love her more than anything. Even though she hasn't said a word to me, I still wish her the best and hope she finds happiness. I know that without her, I never really will. She was perfect for me, but I wasn't interesting and optimistic enough for her. What I look in the face is the big nothing of my life that is without her. She made me so happy and gave my life meaning, and now that's gone. I'll never stop loving her, but even though it's so selfish, I'll always be depressed that she doesn't love me anymore. The lesson to be learned here is two fold: 1.) Nothing lasts forever, especially mutual love. If someone says that they'll love you forever, it's probably bullshit. and 2.) Life is ultimately a big nothing: We tell eachother we will lover eachother forever, but it just isn't true, and when it all ends, nothing has meaning.
<bot>: We all lie to eachother and falsely believe that our love is forever, but it isn't, nothing lasts forever. Everything comes to an end. The only permanent thing that we have is our despair over this situation.
