Loving the wrong person doesn't mean you're stupid. It was stupid of that person not to appreciate your love. 爱错了人并不意味着你愚蠢。那个人不珍惜你的爱，那是他愚蠢。 If it's not because I can't forget you. Who will fight to your world crowded. 这句话存在语法错误，正确的句子应该是：If it weren't because I can't forget you, who would fight to enter your crowded world. 意思是：如果不是因为我忘不了你，谁会拼命挤进你的世界。
