Pls suggest me something😭need help

So I'm in my cllge first year and there's this guy from another section.We met through a mutual friend and humne chats p thoda bohot baat wagera kiya and flow flow main he was being flirty. Basically he told this frnd of mine ki usko mere saath friendship karni hain ( idk wht sort of friendship he wanna do). wtv so in chats he was being flirty nd all and flow flow main , I've also put the same energy back. But later after 2 days of thoda bohot baat krne k baad.. We also talked ki hum cllge main kahi milke ghumne jayenge and all idk 😭mujhe bohot abhi regret hoo rha hain. Mujhe usse baat nhi krni chahiye thi. It's not like ki woh Banda accha nhi hain. Main usko thik se janti taak nhi ...May be he is a good guy idk. But mujhe usko hopes wagera nhi dene chahiye the. Aab woh mujhe text p text kare jaa rha hain kya karu?😭 Humari same campus , same floor p class hoti hain. Main e uske texts ko seen nhi kiya hain. The thing is that guy is not my type and he wants things to be casual and i don't want anything to be casual with anyone ( am not build for this casual shit ). But main e bhi chat k flow flow main ghumne jaane ka wada kr k gaalti kr di aab kya karuu😭😭 ik meri galti hain but I'm regretting too much. Galti hoo jati hain it's just over text nothin else. Should I ignore him completely? Yaa fir jaake kuch bolu ? Pls suggest -
