What Bean says is exactly what you would do if you were to follow the proper rules of English, and is what you should do in class or if you are writing formally.

In real life, however, you will rarely here 1 all by itself. When you do hear 1 it will often be something like He loves you more than I ever could. The use of case markers in English is a dying art and you will often hear 2 used to mean 1. It is probably best to clear up the ambiguity by supplying the missing portions as supplied by Bean.
