"You're her 'now'"
So were all those other guys. And all the guys that'll come after you. They were all "special" and "wonderful" until they were just another notch on the bedpost. No consideration of past, future, or even the humanity of the men she's going through, or for herself. Just "feelings" and a series of "now's" that she shouldn't be accountable for.
Romanticizing this trash needs to end.
