You're right. The reason why I take iossue with it, is because he later implicates that he will remain with you.

"I can scarcely imagine my life without you now."

"I belong at your side."

If he truly means that their relationship is fluid, then it should not just apply to the player, but to him as well. Mostly he is simply in it for his own desires, which are temporary despite these lines implicating otherwise.
