Naaah... Elaine is a lying whore if i've ever seen one. That said, i guess at some point if you take her route she would have a change of heart and would start to really care about the MC, but for now she's keeping her cards really close to her chest and playing her own game, that's for sure. Flirting with the MC, fucking him, talking about getting close is all a part of the play. Unfortunately for her, it's not hard after the initial intentions of screwing him over, to fall under his spell and taking the "disco stick for life" route.
