Yes that’s what i also meant...the woman is just looking out for her own future. With no spouse, no good relation with in laws and a long lonely future ahead with high costs of living in the US and future medical costs, she may not opt to continue financial support to her in laws. Any major medical emergency would just eat into all her savings and she would have to depend on children which she would want to avoid. Only a really selfless person with high sense of duty would continue financial support. I don’t blame her or judge her to be selfish as she has to look out for herself too. So much uncertainty these days.
