He won’t talk or make plans anymore, I do t want to lose my best friend?

I don't know what to do, my friend and i clicked so well from the beginning and i started to have feelings towards him when he was the only person there for me when i was in the hospital, and i started to treat him like we were dating but i would always tell him we friends but i wanted him to make a move but he never would.
but everything was going well and if felt like we were moving to be something and my ex called me when we were out and I think he noticed it but he didn’t say anything and said him being silent was bc he didn’t feel well and it got me really upset bc i felt he was ignoring me by being quiet and lying on why so later on into the week I finally started to talk to him that Friday after and we hung out and I made plans for that Sunday morning with him and he didn’t stay over that night like we had for the past month and it really upset me again so when Sunday came I ghosted him when he called and texted me to pick me up for the plans we made and later in the day I found he messaged my friend to see if I was ok which got me more upset.

so I texted him a couple hours later telling him we were just friends and he took everything we did together to seriously and how we were best friends and had to stay best friends with no changes and he had to know it was only our friendship, and he told me we were just friends and that he wouldn’t let anything happen again and it made me happy bc I can’t lose him if he’s my friend unlike dating when you break up.

but since he hasn’t talked or tried to make plans and asks for his stuff back and the little we talk he isn’t the same he’s short and isn’t like his normal self towards me.

i got to see him the other day bc i was at a spot he hangs out at often and when i left he didn’t pay much mind no hug or anything he just walked away after he said it was good to see me and to take care

I'm starting to worry that i lost him and i don’t want to lose him what do i do?

He won’t talk or make plans anymore, I do t want to lose my best friend?
