Why does she care? She is the one that told Mahid to go away. also Seher being back will give insha insecurity and she will plot with Husna to separate them. Typical ITV storyline.
Mehid is the one who abandoned her first for that first talaq. And the unnecessary second talaq for "his principals" and forgot he will leave her and her mother to that "beast" called father.
If she was in his responsibility. Seher father would not have attacked her or her mother.
A simple solution would have been to just live in same house but different room until she become 18.

And yes . She care because she still in love with him . Even after the long separation.
And the story clearly moving to be typical itv love triangle story.
