this blessed house

The piece"This Blessed House" by Jhumpa Lahiri was an enjoyable read. I thought the relationship between Twinkle and Sanjeev was really interesting- Sanjeev seems to want Twinkle to be something she clearly is not, and his expectations of her are constantly unsatisfied. Sanjeev's frustrations with Twinkle due of her fascination with the religious pieces found in the house are ongoing. It is also stated "He did not know if he loved her" on page 147, which implies Sanjeev's indecisiveness and insecurities regarding their relationship. I still cannot figure this relationship out, do you think they are compatible or doomed for failure?
