For the past eight months everything is done to excuse/ explain Ak's ping ponging between two men. They created situations to allow her to do this without having too much backlash basically or without having a clear POV.
First they had Abhirogi marraige talks coincide Ak's first Udaipur trip. This was done entirely to give Ak a good reason to move on with Nav. Then every step Ak took with Nav, had to be met with Abhi and Arohi even though there was a clear lack of compatibility in both pairs ( more so Abrogi). Then they did Abhir truth reveal and all of Ak's reasons for pretty much anything went out the bin. Uske baad nothing has made any sense. Who she loves, who she claims to love, who she is doing things for, what her motivations are, nothing.
Now again, to excuse Ak moving on romantically with Abhi they are doing the fast marriages stuff. Once she is married she can do all kinds of romance without there being a lot of backlash from her supposed perfect relationship with Nav. Add to this the preganacy track so even after Nav's death she can continue ping ponging and blaming Abhi for whatever feeling she has.
