21M wanna date someone who's waiting till marriage, am I cooked?

Hey! Not sure if this is the right community to post it, just was looking for some advice. I'm 21M. Never dated. Parents are chill about dating and stuff. I study CSE. Date to marry kinda person. Welp the dating scenario in my city is pretty bad. I even know people who get in relationships just to increase their body counts and break up after. I still as a grown up dude think I wanna keep that number to one person only. Breaking up after that much commitment is just life-trauma and cheating on future wife for me. so I thought its only logical to wait till marriage.
The problem I am facing is how to find someone who shares similar beliefs. The reason why Ive lost hope and came here is I did have crush on someone who shared same beliefs and said caste wd be a problem in the future and thus they didn't pursue me. Talking stuff like this to people is sometimes embarrassing as if they don't think similarly they just judge you or call you immature. I feel like the things I believe are quiet outdated and I might die single.
The thing is I am kind of popular in college right now as I am placed with highest package of current batch and nor I am bad-looking, and I can take advantage of this situation, as most my friends say terese to koi bhi pat jayegi ab, but am confused what to even do, as I am a nerd with 0 social awareness. Any advice wd be appreciated. Thanks!
