Help please!!

Guys once I started reading an FF on here but don't remember it's name. Its Dev writing a letter to Maan telling him to come back as he is dying and the letter speaks of a picture of them three when they were together. Maan and Geet liked eachother but Maan left and then she got with Dev. It also speaks about how Geet tells Dev to give her a child so she can hang on to him..

If somebody kmows which one it is PLEASE tell me!!
