Things that don't make sense!

So I've been watching the show from the start and was enjoying it, am not enjoying it so much now. Few things that don't make sense:

1. They explained the back story of how Veer became Virat; he hated his father, left home, etc. but no explanation or sense in why he was stealing cars? What was the reasoning behind it?

2. They made such a big deal about the mother leaving her husband and her 6 kids; how Anvi had to step up; she came back with the intention to kidnap her 3 young kids to use them for smuggling; was the worst mother ever, etc. and now they have turned the story and made the villain into a bechari who suffers from mood swings and the primary reason for her abandoning her family! It just doesn't make sense because when Hetal ben first appeared, they didn't show a single mood swing and now all of a sudden? Just doesn't make sense!

3. So Percy couldn't keep the cafe open but he had enough money to settle in London? How? No sense there either!

4. Sanjay is unbearable now and Anvita keep tolerating his ridiculous behaviour. He puts her down, demeans her, yet she doesn't say much and takes it. He character is a strong one, someone who won't take bs from anyone, yet with Sanjay it is opposite and doesn't make sense!

I hope Sanjay is exposed soon otherwise the show is going to lose it's charm!
