Ruhi is so selfish- Rohit needs to return to set her in place

Why can’t Arman see Ruhi is so self obsessed with herself that she can go to any extent to keep herself happy. I really wish Rohit returns now I wish with lost memory or something so that her hopes of getting married with Arman come to an end. I really wish Abhira to leave them without telling them anything . Dadisa has just crossed her limits with her verbal abuse everything about her family and Arman has never said a word. Instead it has always been on Abhira to prove herself right.
