He told me where he comes from
That everyone has a gun they're always at war
Where he’s from its very dangerous. Could be symbolism for him being at war with himself within his mind. Alot of people claim they want to move far away and get away from everyone; maybe his world only consists of himself. “everyone” represents himself and the gun could be the danger of his mind? Cool.
This can also be seen literally — she’s in love with someone who is forced to live in a dangerous environment, as opposed to her relatively safe (physically) lifestyle.
