I was paying attention to the lyrics of the song during the bathroom scene and there was an important message today:
Seasons may change but I will always be there in your arms... male voice...
so I'm guessing that during the Mandaar track even if for some reason he decides not to fight to get her back actively, he will always be there for her. If he thinks she wants to go back to him, he will let her go but won't break ties with her. If Mandaar turns out to be bad or fake, then he'll support her in cutting things off and choosing what she wants for herself. In this entire period he will show her that he'll always have her back and that she chooses him, she can always come home to him, into his arms, no questions asked.
Maybe this song also shows how he feels he doesn't deserve her love so sending her back to Mandaar would be the only way he'd feel he could give her back everything he took from her.
