I never felt pallavi was weak before marriage. She alone fought with Raghav for her dukaan even though knowing how powerful he is. Like Raghav she is also very protective when it comes to her family.
After her ex husbands death she stayed with Deshmukh's by choice. She is someone who gives her 100% to her relationships when it comes to love and care. She is someone who likes taking responsibilities. She wasn't dependant on Deshmukh's, they were depending on her.
And going by initial 2-3 episodes everyone in Deshmukh family were nice to her except Sulochana, amruta didn't care much. Mansi was also good with her. She became aastin ki saanp after her breakup.
In Raghavs case it took her time to understand him. Raghav does get insensitive at times, but now she knows his intentions. Unlike pallavi Raghav doesn't know to express his feelings/emotions in words, he always holds back.
