“原谅我这一生不羁放纵爱自由”这句话出自美国诗人E.E. Cummings的诗歌《The Road Not Taken》（《那条未走的路》），原句是：
"I have not taken the road less traveled, but I have traveled the road less taken."
不过，你引用的这句话更接近的是：
"I have not taken the road less traveled, but I have traveled the road less taken."
这是诗人对人生选择的感慨，表达了一种不拘一格、自由奔放的人生态度。
如果你是在引用这句话，可以接上：
"I have not taken the road less traveled, but I have traveled the road less taken."
或者，如果你是在表达一种自由、不羁、爱自由的情感，可以接：
"I have not taken the road less traveled, but I have traveled the road less taken."
如果你是在写诗或者表达某种情感，也可以根据语境稍作变化，比如：
"I have not taken the road less traveled, but I have traveled the road less taken."
