Need advice with my situation

I'm a mallu medico 22 m , current a 2nd yr student. So i was this nalla kutty carbon copy guy at school. Have no experience with relationship and romance till now. So i came to college with the same mentality, but i messed up somewhere and kinda proposed a girls. Both said no. Actually the 1st one was like my batchmates were teasing me with her name and she asked me like nnk nthelm ishthm indo enn. And she rejected me. I had zero conversation skill back thia time and afyer 6 months kinda i proposed thia girl wh has been my crush in person. And she also said no . I swar i haven't intentionally hurt anybody till this day and i am frnds with both of them.

So fast forward i was on like self improvement thing. Kinda feel that I'm better than what i was before now. And i decided that I wont be chasing around relationship anymore and have stuck with it for an year now.

But i have a phobia that I'll stay single till the day my parents would eventually go for an arranged marriage. Ive seen my batchmates cheat like actually getting physical even though she was in a 5 yr relationship back home and she kinda broke up with him for a guy who she hardly knew for a month.and they broke up. Dont wanna be that guy who'll get engaged to someone whose been though multiple relationship and situationships.

Also theres this girl whose a family frnd of mine. She's kinda same age as mine and she's also a medico . we both are in different cities both in kerala. Have never talked with her like ever and juat know her name and that shes a medico and its the same for her too. Even though I've been sticking to my no relationship thing i kinda have developed a crush on her. And i put a request on ig and she accepted. Waited for qyite the time and asked one of my closest frnd for advice on the day i saw her at the bus station. He recommended sending a text that i sqw her father at the bua stop. (Yup i know i fked up🙂) and then i unsent that only hi remaining in the chat. She hasn't opened the msg its been like a week now. What should i do. I have not double texted her or anything after that.
