"I will always love you."

Translation: मैं तुमसे हमेशा प्यार करूँगा।

[Sivapriya15]

Duo does not accept "प्रेम" as love. प्रेम is the ultimate love, it is divine love. There is no higher love. हर हर महादेव

"मैं आपसे हमेशा प्रेम करुँगी" जय भोले शंकर

[HafizAhmad5]

My sentence
मैं हमेशा पुमसे पयार करूँगा
Is also right
You can not mark it wrong

[Zerenei]

तुमसे, you wrote पुमसे, maybe there's the issue?
