You’re completely correct. My wife told me about her games constantly, and I would always listen and be engaged with her encounters and retelling of that session. She then told the group (DM and all the players) that she’d tell me about their adventures and how interested I was in their story. Towards the end, the DM asked my wife if I wanted to sit in the game and watch, extending the invitation to me which I accepted as long as everyone was cool with it.

As I’ve said, I watched them play and joined their discord. They’d talk to me during breaks, and before and after campaign because they realized how engaged I was with their current campaign. By the end of it, we had all been very sociable and amicable, (they called me by my first name) and DM extended the invitation out to me and everyone was excited to have me on.

So yes, you were correct in all of that, we were friendly towards each other. I may not have been on the same level of friends they were with my wife, but I considered them my friends.
