I agree, it doesn't look like she left because of money. Plus, they are definitely going to reunite mother and son so her reasons wouldn't be that shallow.
Yeah, looks like Bua is either a widow or divorcee. Did they explain why she wasn't there for Shivansh's sangeet? Did he recently move in? The way they introduced Robin and Malati (?) I thought he was here for quite some time so technically Bua and Tanya should have been here and not in another city? I skipped plenty of scenes before their marriage so I'm not clear about it.
Bua and Tanya's flight was delayed. They even apologise to Shivansh.
