I hooked up with my friend and I dont know how to handle the situation

Me (18F) and my friend (21M) have known each other for two years now. It’s never been a blurred friendship as far as i could tell, we would just hang out and go to parties, both alone and with our mutual acquaintances. It’s always been a light and fun time, and we’ve gotten really close on our one-on-one time.
I just graduated and i will move away soon. In the past two months we’ve been spending a lot of time together and some time ago he tried to kiss me, when i rejected him he blamed it on being tired and high (weed), we usually smoke when we hang out.
then the next time we saw each other we ended up kissing. I made sure to tell him that i dont want our friendship to change, and he agreed. The following time we saw each other it happened again and things got really heated, but he knows that i dont feel ready for sex, since we talked about it several times and he knows i’m really inexperienced on that regard. So when things got “serious” he stopped kissing me and he said “I really want to have sex so we have to stop”. Then he took me home and we kissed goodbye.
Now, previous to that we would see each other basically every other night, but after that day for this past week or so he’s been making up excuses not to see me. He would say he’s tired (but normally he had no problem picking me up at night to hang out) or that he was busy (but usually we would hang out together anyways when we were done seeing other people.) so finally on friday i asked him what was going on, and he said that if we were to see each other, he would want to have sex and he knows that’s not on the table, that the other stuff wasnt an excuse but part of the reason why we werent seeing each other. i told him that i did want to see him anyway even as friends if he didnt wanna continue being physical, but he said he doesnt know what to tell me the it’s not that he “doesnt want” and he already explained, and then wouldnt reply anymore. I just dont know what to think or do, and would really appreciate a word of advice. I do think he loves me as a friend and like i said our bond used to be strong.. Should i try to salvage the friendship or let it fade?
