No alya wont try to get back manik bcoz she clearly knows manik is in love with nandu n she is moved on with dhruv. Yeah dey do ve misunderstanding even after getting intimated bcoz just to make alya realise intimation is not solution for the problems. No dat sentence was not to get manik back but secure her relationship with dhruv bcoz indirectly he is thinking of helping nandini, alya is jealous of dis. If u ve observed, the look wich dhruv gave to alya after saying dat was different. She will never go back to manik. She is just pissed bcoz nandu is related to her past-manik n also her future-dhruv, her situation is really awkward n she is not able accept the fact. Alya is bit grey bt she is not characterless. Alya was pissed bcoz manik gave importance to nandu more fab5, so its very natural for her to be pissed bcoz manik's priority were always fab5 bt now der is someone who is equal to fab5. Alya is orphan, fab5 is her oly family, if fab5 breaks, alya will ve nothing in her life. She is just insecure of nandini getting more importance might break fab5.
Regarding Dhrulya conflict, der is lot more to come in der conflict. Dhruv is 1st of all pissed with her for not letting der relationship to know publically n he is insecure n jealous dat alya doesn't think him capable bt acc to alya she wants to hide bcoz she is scared of loosing him, she doesn't want to go public soon, she wants to explore dhruv. Dhrulya will ve big conflict wen dhruv will come to know dat alya pushed him towards nandu to get back manik. Der story is very interesting if cvs give bit importance to dem.
