Apart from the obvious (she's singing about a guy who called it a night when they were texting/messaging), I think by "chasing pirates", she is referring to the guy as a pirate. By pirate, she may mean that the guy is after someone other than her; he may be chasing gold diggers, hence "pirate". So she's chasing someone who is chasing someone else
