I'm still not sure if I'm ready to call him selfish. But, I do have a feeling that down the line, Dubey uncle might change his stance and side with Prashanth. It seems Dubey uncle has no opinion of his own. I hope Dubey doesn't try to influence Arti to come back to Prashanth in the future (I know this might sound like a ridiculous idea to you guys. I'm just afraid).
I really want Arti to erase Prashanth's name from her life, heart, and mind ASAP and move on in life with Yash.
