So crazy thing happened today

So a bit of a background, I like my classmate(from childhood) she’s my crush from a very long time like literally from when we were from 6th standard. I never really told her, but I did recently. She’s not ready for anything, she’s sorting her career out. But she has a nice opinion on me and we are friends now, she told me not to keep high hopes and later feel bad, but I’m on high hopes(idk I like her a looooottt)

So yesterday my mom called me and said she wanted to ask me something, when I asked what is it she said, today is amavasya I’ll ask later. I knew something was up, maybe something related to some rishtha, but I already told her that there shouldn’t be marriage topic for another two or three years( I’m just 24 now)

Today I asked her again, she said ki it’s about marriage proposal, I knew it. Why ma, I told I’m not interested now and all. She asked me ki do you have anything against intercaste, what ma I don’t have anything like that

Then she asked me, you know your classmate xxxx, what’s your opinion on her. I … ….., I went blank man. Any person would’ve.

So she was telling me that she liked her, and she’s a nice girl and I saw her sometime back, I wanted to ask you before maybe telling a mutual to ask their parents about this.

I said don’t do anything, if I have something I’ll do it from my end, if she gets to know that this happened how would I show my face, we are classmates and friends no.

She was asking me my opinion, I tried to evade the answer but anyone would have easily got the answer from my evasion.

I think what I did is correct but idk, you guys tell me.
It’s not like, I don’t want to marry her, the answer yes was in my throat, but I couldn’t do it, because idk I felt like it’s like going behind her back no?
