Secretly in love with my best friend who passed away

I just need to get it off my chest. He passed away last year. He was gay and I'm a woman so there's no way we would have ever actually gotten together but he was the sweetest, kindest person I've ever met, and even though my feelings wouldn't have been reciprocated I was happy enough just being his friend.

I never told anyone when he was alive and still haven't. I was in a relationship with someone when the feelings developed and I'm still with him. Since nothing was ever gonna happen with my best friend I just always hoped that those feelings would fade in time.

My partner has been extremely supportive through all of this and I know he really cared for my best friend too. I don't want to hurt him any more by telling him all of this but I feel horrible keeping it from him at the same time.
