Why did Akanksha marry Manav?

Well, according to the flashbacks, we know that that Akanksha married Manav to avoid getting married to her sister's B-I-L. She didn't want to end up in a middle class household.. etc..etc..

But she would have already known that Manav was this goody two shoes guy and also middle class.

Why couldn't she just continue her modelling career without marrying anyone. She could just run away from her house/wedding like Silk Smitha did while pursuing her dreams.

Was there any reason?

This side has not been explored yet but at that time people were against his father due to bribery scandal and A was outcasted from the modeling world. She did not have the means to stand on her own
