Doubt she will. Is the chance she's been waiting for years. More than caring&giving Rhea a good education,was there to look at Abhi. 😔 Plus A is there to manipulate her same as she was with Tanu.
Would be really-really surprising if writers would keep a positive character around Abhigya.
And yes,Abhigya are just using her and anyone else to solve their problems. Too used to live with a third person between them,be it to light their jealousy,be it to help them get back-like Dadi,Kiara,Purab-Disha etc.
Anyway want one of them to make the move,he can back off the wedding or she can show her possessiveness as Pragya Mehra.
