Am I in an Unhealthy friendship?

Just a bit disclaimer: My 'Friend' isn't toxic, abusive, a creep, and any other stuff. And I don't want to reveal his user or his name (idek his real name) also sorry for my bad grammar but I hope you understand this..

But's here's the thing, our friendship wasn't really that interesting, we only talk at discord and for some reason I have no connection to him, He seem nice but he's really boring, Whenever I say "You wanna ask something" or "You wanna ask questions" he always said "Nah I'm good", 

but the reason why I keep saying this to him so that I would try to connect with him so that I would get his interests, He never shared anything interesting, and that's why I don't wanna be friends with him, But at the same time I should be staying friends with him cuz

I always think he's lonely nor he doesn't have any friends. I haven't been honest with him about it But I don't wanna be rude to him and I was afraid that I will hurt his feelings, so I guess we're staying friends like this?

 So I realize on I was in unhealthy friendship. Yet again I did want to be rude or hurt his feelings... Should I confess about it or maybe not? Just let me know..
