The only logical thing (in the already illogical, messed up show) would be Anupama-Anuj separation due to something happening to Choti Anu (serious mental health issues, anxiety, fear etc.) fuelled by her messed up priorities.
Since she has separated from Kapadias and is no use now, is seen to be dusregarded and distanced by Shahs.
Anupama suddenly remembers her biological mother Kanta and brother Bhavesh who, this time, take her in strictly temporarily with a deadline to make something of her life and Udaan or whatever else.
May be the new found beta-like Tapish helps with her travel for some shows etc. and because that us Not enough to sustain a living in (what seems like NY) Amreeka, she does odd jobs.
