Pakhi and Virat are not ever destined to be together. When P dreams of being pregnant and wakes up at Sai's voice, P comments about it abb mera khwaab pura hoga. She may come hair breadth close but her khwaab kabhi sach nahi ho payenge. Normal people give up or move on, but she is in Sai's words "Pakhi didi aap bhi kuch kam ziddi nahi hai".
Yes it will not happen, unlike P we know right from early on, when she met V, kismet has been "protecting" V from her. Rephrasing the famous dialogue "zarre zarre ne door karne ki saazish ki hai".
- At Yoga at registration, when she slips and falls into his arms, the kapoos flower lands on V's shoulder simultaneously lands on Sai's shoulder.
- At Yoga camp during the full moon night yoga session, tum aur mein hum ban sakte hai? before V could answer he was called for duty. (even tho he was ready to say yes)
- Her number was wiped out from his hand, literally hatheli se P ki rekhae mita di gayi.
- sone pe suhaga V's phone was smashed
- During the welcome ceremony, V was trying to recognize the ph voice, but Sai interrupted it (first time Sai interrupts)
- Ofc they meet again only after she is betrothed to his brother. So forever distance created. (tho he confessed that he loves her and eventually the famous vaada)
- In GC days, even V-P ph calls were always interrupted by Devi, Aai, Karishma, Sai, Aaba's death, even the attack on V by Vittal
- Another dream by P during her wedding ceremony of V tying magalsutra is shattered by KJ's call regarding Sai's kidnap.
- bachelor V's final ph call to P before leaving GC, was interrupted by UM regarding Sai's suicide.
Well, the list goes on ...
Even if marriage is proposed by fam, even if BK agrees for a widow's remarriage (she was adamant Samrat ki widwa ban kar rahegi, humari tarah widwa), even if all preparations are made, the sindoor, magalsutra and 7 phere dont see happening.
She is fighting a lost cause. She maybe successful in keeping them apart for a while but never be with him.
She may have brought her expectations down, from lover to wife to dost to "tumhari zindagi ke aham faisle mein shamil hu" to "mere nazro ke samne" to becoming mother of his child even if it is not hers (who wants to go thru child bearing when it is not yours), to blackmail for attention, to "kaise bhi halath mein rah longi, baithne ko kaho toh baith jaongi, uthne ko kaho toh uth jaoingi" level.
Yet ...
