Long distance like-relationship???

Dear Anon, So I’m 16 and I’ve never had a boyfriend and I’m not really sure if I want to. Sometime in February this guy I liked and I confessed our feelings for each other and (finally; we’ve liked each other since last year May😔) but we didn’t really talk about it. But like everyone assumed we were dating and we did spend a lot of time together(we never texted or called during our entire friendship) and he was mine and I was his and all that mush stuff(I’ve never been the emotional romantic type), we never kissed; just hugs and pecks on the cheeks-perfectly innocent. Then in July(I had spent most of June on a trip with my family) we graduated from school...we still never texted but I went over to his and he came over to mine-with our other friends. Then he went to school in China and I went to the UK and at first he texted me like everyday despite the time difference, then it started to reduce and I didn’t want to get all paranoid because we had both promised that our education would be our number one priority. Then we had this group video call after not communicating for like a month; then he said something babe and I don’t even know why I said this but I was like I don’t even know why you said that. Then suddenly it was just us two in the video call and it was really awkward for like a minute then I just asked him about school and why he was still awake (i was 6am in China on a Saturday) then for some unknown reason I left the call unannounced. After that video call he messaged me but like at all awkward times so by the time I could reply he couldn’t or he didn’t want to. Anyways, I did some thinking and decided(maybe foolishly) there was no point because even if we somehow managed to get through this we would never end up together 💔 we are from different backgrounds.

Now I just want our friendship back and I don’t know how to go about it, I also want to stop having flashbacks of all the things we said and did together-we practically spent everyday together and even bloody Chemistry reminds me of some odd argument we had or all our experiment fails. Lastly how do I prevent myself from a predicament like this?

Well this was long... but please can you advice me?
