Answer 2

If he's already asked you if you love him, you might want to preface your response with something like "si" or "que si" as in, "¿Que si te amo? No, tal vez algún día." Or maybe just say, "¿Amarte? No,..." Otherwise, it sounds a bit off to me.

Answer 3

the NO seems pretty straightforward and unambiguous. I suppose that you have some feelings for him to qualify the No with a . Your answer is not going to be clear when you qualify it with a nebulous possibility. You need to provide him with more context concerning your present feelings and expanding on your desire to not end, but further explore your relationship.
As far as the grammar...it is ¿Te quiero? or you might want to use amar ¿Te amo'
