One thing i've learned, is that when a guy says that to a girl, he's either using it to manipulate her, or he's going to really do it no matter the girl does. I've learned that from experience. I've had guys pull that on me quite a bit. Plus, my dad, who's almost 80, still pulls that crap on my stepmother. The only reason she's stayed with him for 45 years of abuse is because, every time she tries to leave, he cries suicide.
