Why can't these people communicate!

This is not a bashing post. A sincere question:

Why can not these people communicate with each other.

Zoya-Asad: Both of them are so much in love, pain and clearly they can not live without the other then as a general courtsey to Asad ( who has been so miserable thinking he did hurt zoya immensly with tanu) , how come zoya can not share everything with asad what tanu did. Wether he believes it or not is his problem but shouldn't she tell him that he is innocent and how Tanu had challenged her and all her wrongdoings ( reminding him of blood change samples/ chandelier fiasco/her fear for doctor/her so called husband's attackes whenever asad wanted to say something to zoya, how tanu tried to kill her- wall and cliff scences etc)

Asad-Zoya: Same as above. After doing all that emotional confessional about giving him and their relationship a second chance, can't he at leaf share with zoya that why he is deciding to be with tan veer and the reason of being her pregant with asad's child ( which he thinks is his)

Zoya-Dilshaad/Najama: After knowing Tanveer's vicious intentions, the least zoya could do is share everything with dilshaad/ najama and warn them about her when she call dished her ammi.

Rashid-Dishaad/Asad:

After knowing what happened with asad/ zoya wedding shouldn't rashid communicate his doubts regarding tanu to either asad or dilshaad.

Badi Bi/Ayan/Nikhat:

After knowing Razia's truth shouldn't she communicate this with Ayaan/ Nikhat. As there is no hope from Rashid/ Shireen.

Enough said already in the forum about CV's butchering all the characters to the new level( except razia/Tanu), showing them with no common sense/logic at all.

Also if Tanu puts a condition for zoya to go from asad's life forever if tanu gives her father's address, why zoya has to fulfill the promise. Tanu has broken trust and been doing foul play and knowing this if zoya decides to become so honorable and fulfill tanu's promise ( if cv's show that ) it is non believable but hilarious as well..

Zoya should get her father's address from tanu and expose her with full force. That will be good lesson for tanu.
