Hans writes about the quiet ache of a relationship that didn't last. At first, the speaker prays every day that the two of them are right for each other. The line "i really do" sounds almost like a plea, as if saying it more firmly might make it come true.
Then the tone shifts. "But now, we drifted apart" is short and flat, with no drama or blame. Nothing explodes here; the two people simply move away from each other. In the last lines, the speaker is still trying to accept that the other person isn't right for them, and admits that it's hard. The word "till now" suggests this is not a finished process, and the hurt is still present.
The mood is sad but gentle, honest and resigned. The title, "my prayer," changes meaning along the way: it begins as a hope for love and ends as a struggle to let go.
