I'm in a dilemma to ask a girl

During the way back to hostel, I met this girl.

At first' I didn't actually noticed her all friends were there in the seat section, so she came with her friend whom ik and knows but Idk it's friend or mostly an acquaintance but my friends are friends with her .

So This girl I was talking about has seen some of my friend. But just a hi prolly seen 1 time not more than that..

So when I entered I didn't even look at her face tbh, I sat next to her without any intention and was worried as how to not sit awkward as a girl's next to me.

So as I mentioned some of the friends mine who started asking her name all the stuff , so in my mind I'm saying avanmar pani thudangi.. then the Convo was over, then after the a few minutes she started talking to me , like she asked something and conversation hit it off. I'm very bad when it comes talking to girls , (maybe my bs about myself or true) so then till the destination station we talked continuously.

Like 1st avalodu name okke chodichavar enne nokki tease aakkunnu.. like we taking till the train stopped, just general things, like i got to know about family, even the food she likes and hate, about her pg.. all things.

We Are in college but different course, so we have different blocks for that so we don't see that often..

Then once we reached she said bye , and I walked with my friends , they were telling me they didn't knew I had this skill. Like at the moment I felt like I'm at the peak but didn't expressed , but Njan kooduthal swayam pongiyille.

Pinne friend started teasing me with her name as Njan nokkunna penn like that where I actually didn't..

So pinne njan , when i thought about it I felt like I do like her, idk it's whether because of my friend's constant teasing, but I do like her..

But the thing that holds me back is like she's hindu, and I'm christian, during our Convo she mentioned about a friend of her like christian and hindu different religions and Said onnu alochichu nokkiye about them like that... I don't blame anyone, also I can manage somehow with my parents on Hindu, but she's like a proper aayi vratham okke edukkunna kutty aanu, so I'm in a confusion, also after the 1st meeting in train we met 2 times in train again,and it's been over month since I saw her ,as she's in science they got study holidays early .

She doesn't even know that I like her , also I'm in fear..

I didn't even told her...

Cause in my school days what I felt when people say some class mates are in love I felt disgusted, most of the friends too, so I didn't talked A lot if girls, like that..then prema vivaham thett aanennunu okke thonniya sajayam so my interaction is shit.. also never had relationship and bhayam like that...
