Should i delete and throw away everything i have of him?

I met him last year in the beginning we were just friends but slowly I fell in love with him I have never felt this way with anyone before not even my exes. He said he really likes me too and wants me in his life but he is not ready for a serious relationship. We havent slept together because of that and like I dont do fwbs. He said he wants to see whats out there and doesnt want to feel restricted but another day he said he doesnt want anyone else but me another day he said all the things he feels about me he has not felt with another girl. My bff tells me that he is very unsure and that isnt a good sign for his age hes 21. Next week he is moving few hours away to start university. But he says he would still like to call me every now and then and for us to still be in touch but I dont see whats the point. I know he will meet a lot of women there and the thought of him being with someone else makes me sick. I wish he would just end it because I have tried to end it because of our situation and that we will be long distance once he goes away but he begged me not to and take him back.

I have texts, voice messages, pictures, some cards and a stuffed toy from him all of it is so special to me and it would pain me so much to get rid of it all especially our texts and all the sweet things he said to me but wondering if this is what I need to do so I can move on and get over my feelings even though we will talk on the phone every month but it will probably be as friends. I dont know I dont want to hold on to the dream of something thats probably never going to happen and as long as I do I wont be able to like anyone else. I really dont know what to do and its making me feel so anxious and stuck.
