I still dont understand "LOVE"

What is "LOVE"?
It takes alot of courage to love someone. How much courage do I have to be hurt by you. Everytime when I plunge into the river of love, everytime I drown in it. haha... Why? I dont know. "I want you to be my girlfriend because I think/know that you are a nice girl. You'll be a good girlfriend. You're wat I always hope for. So could you accept me and let me love you the way you deserve? You'll be the one who'll not break my heart so let me mend your broken heart and let you trust love again. Can you love me? Can you accept me?" Those lines... those lines of lies...I've heard them more than every heart break. Those after me, those I've accepted, those I've rejected. Why do all of you tell me the same? but when I really gave you a chance you broke my heart yet again. Do you not mean what all of you had said before? I'm sorry...I'm sorry I cant trust these lines anymore...sorry for those who are after me now. Maybe I'm not a good gf...or there's something wrong with me tat's why they all left me. Maybe I make them feel pressured...or I'm too hard to take care of... I dont know. Maybe I just blame myself...

张学友 - 我真的受伤了

窗外阴天了　音乐低声了
我的心开始想你了

灯光也暗了　音乐低声了
口中的棉花糖也融化了
窗外阴天了　人是无聊了
我的心开始想你了

电话响起了　你要说话了
还以为你心里对我又想念了
怎么你声音变得冷淡了
是你变了　是你变了

灯光熄灭了　音乐静止了
滴下的眼泪已停不住了
天下起雨了　人是不快乐
我的心真的受伤了
