PLEASE HELP ME TO FIND THIS MOVIE🙏🙏

I’m starting to think i made this movie up but i KNOW i saw it. So basically there is this couple who goes climbing but the girl falls/a rock hits her and she’s dying/dead. Her husband/boyfriend goes to help her but she’s unconscious/dead so he prays to god something like “take me instead of her” and she survives but she forgets who her husband/boyfriend is. Anyway i remember that in the end the guy either finds out he’s an angel or he is asked by god(?) to be one. Sadly that’s all i remember pls if someone knows this movie tell me the title cuz i’m going crazy. thanks 🙏🙏
