What does Chachaji mean by 'Bharosa/TRUST'

I am confused about what chachaji means by the word "Bharosa exactly.

Cinema hall incident
Some days agao when Chachiji caught Naina at Cinema hall, then she was angry at Naina for breaking the trust. But Chachaji took it coolly. He said, Naina hid this coz if Nain would tell them about movie, then chachi would not allow her to go to movie. He said, they need to be friend to their kids. So that they will not hide anything. So, He was considerate.

Sharing about falling in love
Now, chachaji expects Naina to tell him about her love, the moment she falls in love and discuss it with him before taking this any further as he said last day, "Agar aisa hota toh Naina jorur mujhe batati". That's where he trusts her.
But the question is, why can't be considerate in this matter too! When a teenager falls in love it is natural for him/her to hide this. Naina can't immediately come to chachaji to discuss this. It is a sensitive issue. Why he won't be considerate here?

Caste issue
And the issue about Agarwals vs. Maheshwaris now. For Arjun's incident chachaji asked Arjun, whether he really loves Shefali. He gave Arjun chance to say, but Arjun denied and humiliated Shefali which was truly understood by Chachaji. That's where chachaji thought Arjun broke the trust.
Would he really not accept Shejun if Arjun said truth?
Would he really think that Naina broke the trust if she would have come and say she loves a Maheshwari! Would he oppose that?

All these questions are making me confused what chachaji exactly means by Bharosa/Trust from Naina.
All the forum friends can you please share your views and enlighten me in this matter! [)]

I was confused too.
I truly think Chachaji is the sensible person in Agarwal house. He doesn't rush things he always understands Naina. Though I hate when Tai jii without any knowledge raise her hand on Naina. Why does she? Because she's poor? She don't have a mother? Looks like she takes out Rakesh gussa on poor Naina.

Chachajee all the time given lecture on trust making Naina decision more firm .He always been shown as sensible person but I think this Arjun incident actuaally affected him as well ...but I still think ,he will be the first person who gonna support Sameer and naina relation in future

Looking at the character sketch of chachaji all I could think now is hopefully he meant that Naina will consider him while taking any decisions and also wont take any wrong path: elope or secret marriage but would share everything with him just like a friend.

Leave chachaji yaar I'm totally confused with the whole agarwal and maheshwari mess. Chachaji moves are not able to be deciphered. Sometimes he is OK with movie plan and he even invited Swathi for naina B-Day party after knowing munna Swathi issue. He was k with that then the way he reacted yesterday I didn't think so he was happy if chachiji haven't told naina ki koi galthi nahi hey tho he calmed down bit initially he was angry.

Chachaji is too much into this bharosa thing and when he'll come to know about Samaina...he would be shattered initially but later he would support her as he would realise that her happiness lies with him😊

Thanks all.

For chachaji, Naina has become his 'guroor', more than his abhimaan ---fortunately or unfortunately!! we all loved the support and sane advice he would give.. let us how teh whole family comes of the blow dealt by Arjun especially chacha and chachi..
