I genuinely don't know how to address them, I usually go for their first name, but I assume if we grew close enough I could see myself calling them mum or dad.

No! I think that’s really really wrong.

Yeah I say Pa or Papi sometimes

The mother of my girlfriend and I have a long standing lovely relationship also during the time my girlfriend and I paused our relationship. I could pretty much move in to her any time at night when I am in distress. We have an almost 2nd daughter relationship. In times of misery she has been a wonder of support and care for me.

No, call them both daddy or get out

I only met and spoke to my in-laws once, and I only called them by their names. When I met them, my wife was actually meeting her step father for the first time because her family had no contact with her for so long.

Nonono. That would feel odd to me.

Would I? Hmmm I feel like they'd need to earn it. Not to be a dick, but you don't become a mum or dad overnight unless you're the actuals.

I wouldn't

I wouldn't

No...

That would be too strange for me tbh

I call mum and dad to other than people, but in aramaic.

I haven't, my last GF's dad was just Joe...if it meant something to them I could but it would be weird as I never in my life called anyone that

no
