What is your question?
I used to have a huge crush on this guy, but then I stopped liking him, but I don't know how to tell them, cause I think they still think I like them and I think they like me, how do I let them down easily? PS no one has ever liked me and we are really good friends so I don't want to ruin that...
Dear Let them down lightly,
What a good question! Good thing I know how to answer! Ok so first if you guys are truly friends then they will understand and will want to stay friends. You could also tell him you don’t like them anymore and because you aren’t sure if they like you you won't have to bring up them liking you and you can continue being friends.
Another word of advice is it's only awkward if you make it awkward. If you avoid them or act differently in a bad way around them it's just going to make everything more awkward than it needs to be. And maybe acting more yourself around them can show them you're more of a friend to them instead of a crush.
It all really comes down to what your relationship looks like, like how good of friends you are and how serious the crush was.
