Is there a such thing as falling out of love with someone?

It’s interesting cause I actually fell in love with a man but we never had sex.
There’s a big age gap. BUT We connected spiritually, emotionally and he was my closest friend. It’s been a year and a half since we slowed down talking as much. He still has a special place in my heart. No matter how we argue.
I've expressed some of feelings to him. He never says he does or doesn’t feel the same.
But I know for a fact he loves me the way he’s cared for me, been there for me. He used to do the things a man does for a woman he loves. I don't know if I got the wrong message.

The way he made me feel without touching me sexually is so special.

I need to move on with my life. But I can’t completely cut him out my life he’s like family to me.
But I don’t think I could have him as a boyfriend or husband. Just the circumstances.
SO again, can we fall out of love with someone, if so how do you do that?
