Temporarily Deactivated my Insta

I(22m) just Deactivated my Instagram as I was yesterday looking at my activity details on phone and turns out I am spending on average of 5 hr on Instagram. As my college are having vacations as we just ended our sem but still 5 hr on insta!! No excuse to that but there is a catch I use to talk to a girl on Instagram like on daily basis..there would not be a single day when she has not texted me "Had your dinner? " Yupp that's how we daily use to start our conversation and then use to talk about every random things possible..I like talking to her but also I fear the social media addiction..I am afraid that what if I developed a habit of talking to her. From my side we are just friends nothing more nothing less but, now I kinda developed a habit of her.. without her talking to me , describing her day to me I feel empty and that's bad I don't want that. She is very perfect..ok I lied I am slowly developing some feelings for her but she is too good to be true. Like one day I had fever and she literally called a doctor asked for what kind of medicine I can take for my symptoms and send me that priscription as we live so distant like in different cities.. She is so caring and loving. I don't want to loose that but now as I have Deactivated my Instagram it's hard even to think my life without her asking "Had you dinner ?" But at the same time using Instagram for 5hrs is not me I use to be that guy who don't use any social media application and that's why she and I got so close like she use to teach me how Instagram works and all this is not right What should I do now?? PS :- I know I should have asked her for her number so that we could talk on WhatsApp but here's the thing She is too good and loving and caring and so so beautiful, She definitely deserves someone way better than me and I want her to have the best I am just a random nobody she is very popular in her college and has so many friends In a way it's good that we stopped talking by this at least now she will find someone else way better than me to talk and share things.
