Yup. It's about a friend having an affair with his wife.
Since they are both people he cares about, he hopes they can be happy with each other even if they did both screw him over. He just simply wants nothing to do with either of them though, which is why there's "nothing left to do".
The chorus really captures the feeling of his reluctant selflessness.
Not so sure about the murder thing though. "House of pain" means emotional pain. It's a good way to make the lines about the trenches make sense, though. But the rest of the song doesn't really give off that brutal of a vibe.
