What does it mean you unfriend someone on snapchat, and when you search them up it says " accept friend"?

I added the guy i like on snapchat awhile ago and then a week later he added me back. then i found out he had unfollowed me on insta the same day. so i unfriended him. When i went to go search him up it says "accept friend" under his user.. what does that mean? does he still have me as his? i don't have his name on his contacts so when i typed it in, it only said "add friend" under his user... which is confusing. When i search him up it says accept friend, but when i have him on my contacts it says add friend lol. so i'm just curious what the accept friend mean.. and if he'll know that i re-added him even though i'm still on his friend list
