求翻译：我们在一起的时候，我没做到应该做的，你不告而别的时候，我确实恨过你，但现在，我更恨自己，我不是一个合格的男朋友，但现在我长大了，我懂得怎样去做了，你以前不是想听我唱歌吗，我现在唱吧。是什么意思？

When we are together, I did not do it should do, when you take leave, I really hated you, but now, I hate myself, I am not a qualified boyfriend, but I grew up , I know how to do it, you've not want to hear me sing, I sing.

We are in a time when, I did not do what we should be doing, you do not report any other time, and I really hate you, but for now, I hate myself, I am not a qualified her boyfriend, but now I have grown up, and I know how to do so, you do not want to listen to my singing, I sing it now.

We at together time, I have not achieved should do, but you do not consider other time, I have hated you truly, but the present, I hate oneself, I am not a qualified boyfriend, but I have grown up now, I understood how has done, you before is not wants to listen to me to sing, I sing now.

Our time together, I didn't make it should be done, without you and other times, I really hate you, but now I hate myself, I'm not a qualified boyfriends, but now I'm grown up, I know how to do it, you do not want to hear me sing, I sing right now.
