No one, who isn't monogamous, would say "I would always want more of you than you'd have to spare." And there's nothing in all of act 1 or 2 to engage in anything other than monogamy with her because she always shuts the idea down.
This is how her writing is established, to do a 180 so suddenly in act 3 is bad writing period. We all know the only reason they made SH into it is because she's a hot half elf and they needed to add some porn. Let's not delude ourselves into thinking it's anything more than that lol
