Video chat?

The key is whether the person is dressed and the relationship. Video calling from bed with a friend can feel intimate. If you want to avoid that grey area, I personally use stranger chat for anonymous, no strings attached conversations. It keeps things clear.

She was sitting up in bed naked with shoulders exposed and the duvet covering her chest? I would not be comfortable with that. It’s too intimate and over-familiar.

Would they have done this had they known you were observing? I doubt it.

I would absolutely be mentioning it, @Mattime.

I get what you mean. Honestly, video chatting has gotten pretty casual these days — apps like lemonchat.app make it super easy to connect with random people. Kinda wild how normal it's become! 😄

I wouldn't do this with my male friends, no. And I wouldn't be happy with a partner doing this.

I know on other threads posters have put forward the view that long term opposite sex friendships started before a couple get together aren't generally a problem. However a new female friend made more recently, after a relationship began, has more potential to be problematic. Unless of course effort is made to reassure the partner by including them in the new friendship.
What you describe i.e. your partner only working with the woman for a couple of months and then she has become a very close friend would worry me more. I assume they met after your relationship began? The fact they now think it's normal to talk while she is naked in bed is more concerning given your update.

I think if you've no other cause for concern (over the years) then i suppose there's no issue.

I'd be a bit .... 🤔though.

If it was me and i wanted to say something i'd say ''Noticed z was in her bed when you chatted earlier!'' ... and see what he said.

Of course if he just says ''yeah ....'' in a distracted manner as if he didn't even notice you'll be no better off?

I've often spoken to friends or family from bed. I don't think I would for work.

They seem quite relaxed with each other and like they connected they only worked together a few months and she is happy for him to see her in bed.

I guess if he is still attentive to you and just as loving, and isn't investing more relationship time into her, then do you have anything to be worried about.

I would go along a few times when they meet up, see what's she's like personally

How do they know each other?

What are your ages?

How often does he message her or her him?

Did you ask him why she facetime while naked in bed?

Perhaps it's a generational thing then - boundaries regarding privacy and acceptability have been pushed back tremendously.
Personally I would assume your partner and his friend must have a close friendship if this is normal behaviour for them. How you feel about this is up to you.

All of my DD's (26-38) would do this. Two would with the opposite sex. It seems the norm in their friendship groups. I consider it inappropriate, so wouldn't do it. My sister (68) does, but wearing at least nightwear.

Did she know you were there during the call?

I think messaging from a bedroom is a totally different thing from messaging whilst in bed and possibly not even wearing any clothing are two totally different things.
A few pp are giving instances of work related video calling. I assumed op was not talking about a work related call. I assumed this was a personal conversation between 2 friends.

If she was sitting up in bed hungover in old pyjamas with a cup of tea, scruffy hair and no makeup I wouldn't think anything of it.

If she was smouldering in a silk camisole or naked with a crisp white sheet playfully entwined around her, like a fully made-up influencer in a 'Woke up like this' Instagram post that's a bit different.

As I said, lots of younger people no longer think anything of messaging from their bedrooms because it's what most of them do.

I'm about to join a work Zoom from mine. You'll be relieved to know that I'm wearing a top.

Do they usually video chat?

Did he facetime her and that's where she happened to be? Or she called him from her bed?

This.

I did a speed awareness course from my bed once (poorly). But i put a jumper on ...
