Orobo ji,
To achieve sandys dream of IPS, suraj took the lead and is fighting hard to convince his mom. He supported sandy thru 3 matka challenges, sbc. Even when sandy was ready to give up her dream, he is the one holding on to her dream .
In the same way, samdhya is making sure that suraj's dream of a united family also gets fulfilled. She also will go to any lengths to achieve it. Be it running after babho, giving her foot baths, acting foolish, or pretending to be inept at cooking etc.
In their relationship Cvs cannot show one person taking more and using the other. If suraj makes her IPS, but they leave RP, then it would be like sandhya failed him and used him. So sandhy would try her best to keep suraj united with his mom. Surya know what is imp.to each other and are willing to do anything to make it happen. Surya are secure in their love for each other. They are happy being together and they are solving problem of babho in their own way.
