Soon-to-be spouse keeps posting this poem… should I be worried? [30F][31M]

Need some perspective on something that’s been on my mind. My soon-to-be spouse has been repeatedly posting this Hindi poem on their Instagram story:

जीवन में एक सितारा था

माना वह बेहद प्यारा था

वह डूब गया तो डूब गया

अम्बर के आनन को देखो

कितने इसके तारे टूटे

कितने इसके प्यारे छूटे

जो छूट गए फिर कहाँ मिले

पर बोलो टूटे तारों पर

कब अम्बर शोक मनाता है

जो बीत गई सो बात गई

From what I understand, it roughly means that there was someone or something special in their life but they are gone now and life moves on without mourning forever.

I might be overthinking but it’s making me uncomfortable. It feels like it’s about letting go of someone important from the past. I’m not sure if this is just a general life philosophy or if it could be about a past relationship they are still thinking about. We are about to get married, so this is bothering me more than it normally would.

Am I reading too much into this? Or is this something I should talk to them about directly?
