Hypothetically if mishti is Neils daughter only and if chuhi is positive then also she has to move on with mishti she cannot expect Neil to break his marriage with Avni abandoning her and accepting chuhi and mishti though Neil may have fatherly responsibility and love towards mishti he cannot compromise his life by leaving Avni and marrying chuhi for the sake of mishti none of them will be ultimately happy
True love is not with whom you can live for the rest of the life
But true love is when you can't live without person for the rest of the life
Neils love for chuhi has died long back it was in one way not true love
But Neil's love for Avni is matured he felt that soul mate connection only with Avni
Like Neil himself said once to bebe he was able to move on and live without chuhi but even the thought of losing Avni makes him go mad
So even if Avni leaves Neil forever Neil can never revive his dead feelings and love for chuhi he will always remain as Avni's Neil only which will affect one way or another mishti too
When parents are unhappy with each other how will they give the child happiness and for how long they can act and compromise for mishti
Avni has struggled her entire life she never had someone in her life whom she can never share who rightfully belongs to her in all sense Neil gave life to Avni's feelings and her desire to live a normal life he gave him something which no one ever gave her
A dream of living a happy family
Doesn't she deserve Neil after having given all this test for her love?
Doesn't she deserve a normal and happy family life?
So in any way the only fair and decision Neil could do is to take responsibility of mishti financially and emotionally apart from that he cannot play the role of husband to chuhi even for mishti sake
I believe avneil are soulmates made for each other thats why ultimately mishti is not Neil's daughter even the destiny doesn't want to seperate them put them apart make their lovestory incomplete
It's destiny's game that chuhi and Neil didn't had any physical relationship on that night when both of them were not in their senses
It's destiny's game that chuhi had to leave Neil despite his love for her was true
It's destiny's game that Neil met Avni fell more madly and deeply than ever for her
This proves that avneil are soulmates because lovers can be seperated but who can put two soulmates apart
