Should I walk away

I have my bestfriend who I know him for two years and spend a lot of time tgt because we both international student. He always there for me through the toughest time of my life and he also shared his traumatic stories that he had never told anyone to me as well. 7-8 months ago we both know we have to say goodbye and go back to our home country which make us really sad and he started to spend more time with me more. We slept tgt but no sex just cuddle, we held hands, we kissed and i just feel a bit morethan frds and I felt good actually but I still didnt want to admit it because I dont want to ruin the friendship and I’m scared of losing him since I knew that he is a type of guy that never commit with anyone and he had commitment issues also he always gets bored easily. Until the day we say goodbye which is he asked me that does friend kiss and hug and cry at airport when they say goodbye. I still said yeah maybe… After that we still talk but I always worried that he might change or something. Until last month I have a plan to go to his country because my family gonna go travel so I just went there 3 weeks earlier to meet him. It’s a bit awkward at first and he just said that he never had someone to visit him before even his family never visited him. He stressed and felt like he didnt what to do. So he just said to me that he can hangout with me but not everyday. So I said i came here just to see him and he knew it. He gonna leave me alone like this?. He just shocked and he said what should he do so I decided to travel alone but still met him3-4 days but after that he asked me to stay with him and he said sorry. He tried to makeup with me and cried to me one day because he said that he doesnt want to lose me but he doesnt know how to maintain relationship it’s too hard.

So I just think that okay i wont keep any hopes again about this relationship. I had one week free before I went back to my country he asked me everyday to meet but I always said no because I think i want to move on from this. Normally I texted him alot we talked a lot but I just changed to replied him really slow and he called and asked me so I said I think I will change myself he’s not gonna lose me but i wont be the same person I used to be for him, I’m not gonna contact him that often. He just said that I’m tge first one that make he knows how to take care and how to be loved and when I said like this it made him scared that I might leave him forever. I just said that I need my time but I didnt say that because I liked him and this made me anxious and worried about him all the time. He cried and send me back to my country we cried a lot. He said this is not the last time right? I just silent because i didnt know how to handle. Right now I came back he texted me but i didnt replied for 5 days and then one day i just felt like I missed him a lot. Those 5 days i thought i just tried to deny or jetlag or whatever. But now I miss him and the only things that I’m afraid is if I keep ignore him we r not gonna be friend anymore and he gonna be just my memory. I know that the relationship between us wont develop to be morethan this so i try to move on from it but I still feel like I dont want to lose him and I dont want him to feel bad as well.

what should I do. Just ghost him for a while or try to response him once a day or what should I do. In my head, i always keep thinking about him
