The day I looked forward to ------(come).为什么用came,那什么时候用look forward to doing?
有look forward to do

此处I look forward to 是作为 the day 的后置定语,即修饰 the day,句子的主体架构为the day came——那一天来了.加上 I look forward to,也就是我期待的那一天来了.
由于 to 是介词,所以如果是词组,那么look forward to doing 是固定搭配,不存在 look forward to do 的形式.
关键在于一个句子要句子成分（主谓宾或主系表）完整,否则不能称之为句子.如果是 the day I look forward to coming,那么句子成分不完整,无法构成句子.所以此处用came.
