Its seems to me like she's talking about having an affair, and ends up falling for the guy.
"And I don't care about the girl behind you." - Her not thinking about the 'girl behind him' makes me think of his wife.
Her heart feels bad because she can't have anymore than what he's giving. He will never truely be hers.
"And you don't care how this affair will break me." - She loves him, but knows that sooner or later the thing between the two will be over, and that its going to devastate her.
