Are Pushkar Bani still friends/

What happened to Pushkar & Bnai's friendship. Bnai used to confide in Pushkar about everything. Pushkar used to care about Bnai's wellbeing & happiness.

bani didn't talk to Pushkar about Pia's condition, her decission to protect her from reality & its implication on Pushkar .

i just didn't get why Pushkar told Pia about the baby not being his? She was asking him to marry her which wouldn't change anything.He is married to her already. Why did't he think about the consequences of telling her that for Bani.
