Is it inappropriate to hug a colleague in front of their partner if you always greet with a hug?

I went out somewhere and bumped into a male colleague.

As I've been off for the year on mat leave I've not seen him.

We were both just as excited to see each other.
Anyways he reached his hands out and so did I and did that side hug.
Nothing longer than a few seconds.

Anyways his wife was there and this was my first time meeting her.

And their children, I reached my hand out to shake her hand and she rejected it.

The kids remembered me and gave me high 5's.

I didn't feel odd about hugging him as it's our usual way to greet each other especially as we work in a " family ".

I mean I'm also now 6 months pregnant with my second.

I have had doubts since that I was inappropriate and offended her which wasn't my intention at all. 🫤
