Jyoti continuing to earn for the house was her decision, so it's unfair to blame Padma here. Nobody - not KK, not Padma, not Deepu... expected Jyoti to continue to support them after she got married. In fact, when CM was close to persuading Jyoti to quit taking a salary from Sishu Mangal due to how it was making the Vashisths look - like giving money w/ one hand and taking from the other - Jyoti was actually ready to quit, despite the consequences. Only reason she continued was Pankaj intervening.
But after the heist, Jyoti completely quit Sishu Mangal and there was nothing about her giving any money home. In fact, the bulk of Jyoti's maayka troubles were due to Brij/Sushma. Now, once Sushma gives birth and adapts the baby away, she'll no longer be so much of a burden on Jyoti - as it is, she has a scholarship (isn't it strange how a girl gets a scholarship merely on intent, rather than performance?) Deepu should be able to find a job easily, unless the CVs insist in screwing things up by his refusing to take any job that his sasur-ji gets him. So if Jyoti does leave and either get married to Kabir or return to Pankaj (given the sort of doormat she is, I no longer rule out the latter), she doesn't have to keep supporting her maayka.
Let's see if that's how it continues.
