Guys advice please

When I was 16 I had a 14 year old guy friend from Syria who I had a genuine friend relationship with for years. It never became anything more than that and i never thought of him more than a friend.

Now We’re in our mid 20s and one of my old friends tried saying i groomed him into a relationship :/ . When he turned 20 is when I started to catch feelings for him, I didn’t tell him until a year later. And we’ve been together ever since.

I think it’s absurd because I never “groomed” him into being with me. Not even when we were younger. But this girl thinks guys and girls can’t be friends without fucking or liking each other so I don’t know what the hell went through her mind. I didn’t start to like him until he turned 20. Which wasn’t a Coincidence, it just happened like that. We were friends for soooo long that we both felt some type of way that we both chose to move to the next level.
