I've name changed for this, as I don't ever want anyone to know IRL.
My best friend is a guy who was in my reception class at school - we've been close throughout our whole lives. When we were younger we had a few "moments" - occasionally a drunken kiss, and once we nearly slept together but he ended up backing out because there would be no going back and he didn't want to ruin the friendship.
We remained close into adulthood, I got married and had children, he had a few medium-term relationships, and we were always on good terms with one another's partners. Just really good friends.
Sadly, he passed away from a terminal illness three years ago. Just before he died, he basically told me that he'd always been in love with me but had never been brave enough to do anything about it. I was stunned, I never had any idea.
Three years later and I still think about it all the time. I feel guilty and confused. I always find myself lost in thoughts of what might have been. I never thought that I loved him, but was always attracted to him. I think perhaps I stopped myself from admitting that I did love him for the same reasons; we'd grown up like siblings and anything more would have felt too strange.
I don't know why I'm posting, I just need to get it off my chest because I could never tell anybody IRL. How do I process and get past this?
