Am I a homewrecker?

I've this guy bestfriend who's engaged. He deeply loves his fiancée and I completely respect that.
The thing is, he used to ask me to stay on the phone with him till he falls asleep then, things escalated that we stay all the night sleeping on the phone together, waking up in the middle to casually talk then fall asleep again but recently he asked me to stop doing that because he feels like he's cheating on his fiancée , and we stopped.
He also mentioned how much he wait so we can talk and that he's attached to me "in a friendly way".
He always tells me that he loves me and that I'm beautiful "again, assuring me that he's not meaning it as a romantic interest"
On my behalf, I don't want anything more than friendship. I love talking to him so much. He's the first one I like to inform when anything happens to me and I enjoy everything we do together deeply. I do love him sincerely.
His fiancée doesn't know about our friendship.
My question is , Am I a homewrecker?
