For me, I think it's about two people that were previously in a relationships (on again/off again), and had strong feelings for each other. One of them is worried about their ex, but can't help them because their ex keeps shutting them out and won't talk about it. It could be one of them has moved on (and in another relationship), while the other one is still struggling with the breakup, can't move on and in sadness over not being with the person they love.
