We all knw hw raghav changed after falling in love with kalpi...he turned good ,lively n his arrogance was reducing...n he was full n love...there cn b no place for revenge in heart wen it is filled with love...so he decided to marry kalpi n totally forgot abt his revenge which was his life long ambition...so kalpi has d capacity to change raghav...
But gauri want revenge badly...for dat she has nly support dat is her son raghav...but he was in love n he admire kalpi more than her...if he get married with kalpi..kalpi is a girl with golden heart so she would hv nvr let raghav to take revenge on kapoors...n she also fear for kamla as gauri knws raghav respect kamla n she s kalpi mom...so he will nvr take any decision dat will hurt kalpi n kamla...gauri want her son to obey her orders hence she blackmail him made him to take first step of marrying pakhi and also nt let kalpi knw dis before marriage bcoz she wanted kamla and kalpi hate raghav for his dis action n will b away from his life...so all jadhav will hate raghav n raghav has no option n will listen to gauri n take revenge...
Then y pakhi-gauri bond...its again a big plan i guess...to use pakhi to make sure raghav n kalpi are away for a while inbetween dat time she cn take revenge using her son...anyhw she was sure that raghav will nt fall for pakhi...so till she take all d situation under gauri control she would support pakhi n throw her after dat...
I dnt tnk gauri hate kalpi...after revenge she might arrange marriage for ragna...but till then she want to keep raghav n kalpi away...
Its just my thinking..
Sorry for long post...
