Did I overstep the mark by getting involved with fiancés female friend

[Quickrunner91]

My fiance has had a female friend for a few years. She works with him, and was calling him and texting him after work hours about her relationship issues with her parter. This was making me feel uncomfortable and I asked my fiance if he would let me meet her as a group. He said he asked her but she never got back to him with a date. So I never met her.
One time after this he called her regarding a work related topic. She began venting about her relationship issues. He told me he stopped her, but in a rude way. He didn’t tell me exactly what he said to her. It made her angry and they didn’t speak for some days, but came back to being relatively friendly after some time.
Fast forward a week or two. My fiance is relatively active on facebook. This woman never likes or comments on his facebook posts. My fiance shared a post and she reacted with love to this and both me and my fiance found this odd. He ended up unfriending her of his own accord.
The following day she had kicked him out of a group chat of which she was an admin and blocked him on all media.
My fiance has previously described this woman as not having the nicest of characters and has said she may try to cause him issues at work becuase of this. His work/career is very important to him. She has also previously helped him with work so I feel guilty that I contributed to the loss of this.
Did I overstep a mark here by voicing my concerns?

If this was a friend he met after you started dating this dynamic is very inappropriate and (even if it was before you started dating but even more so if after) I would be livid not with this "friend" but with your fiance for being so intimately emotionally close to another woman that isn't you. That's how emotional affairs begin to happen she goes to him for support about her relationship issues looking for validation from him and he comes in looking like the hero to her saying oh no of course it's not you it's him. It's a slippery slope and I am not sure why his loyalty to you wasn't enough that the minute she started calling/texting him outside of work hours about personal matters he didn't immediately text back and say, "sorry let's please keep this professional"

I would be exploring why in any way shape or form he felt hi behavior with her was in any way appropriate for an engaged man. No sorry that shit would have been shut down so fast and I would have told my fiance unless it's your mother or sister you aren't not to play therapist to some other woman please keep all after hour phone calls and text work related because really why does he feel the need to be more loyal to her than you?

I'm glad to read OP he did stop her but why didn't he stop her the very first time it even began to cross into personal relationship problems territory? The fact he let it go on at all is problematic because some thing like this could arise again.

She probably couldn’t be arsed with getting involved in any drama

you asking to met her is like a cat pissing to mark it territory and insinuating she can’t be trusted

Nope you have it wrong. The very off and weird thing is to be calling up and texting a colleague after work/office hours are through knowing he is engaged about non work related matters. What is her motive for doing that? To get this guy to take time away in the evenings from his fiance to play emotional therapist. You really don't see a problem with this woman venting to another man who is engaged to be married and very much taken about her own personal romantic problems? You don't see the dangerous rabbit hole this can lead to? If this is innocent why does she need to be kept hidden from his fiance?

Nope if I was this dude's fiance this shit would be shut down so fast his head would spin. I would be telling him, "umm no this random woman doesn't need to be calling or texting your phone all hours of the evening/night unless it's work related and let's be real unless he works as emergency personal work related stuff can always wait until you clock in the next morning."

It's highly inappropriate to be calling a work colleague who is an about to be married man after work hours about non work related matters. He should have told her not rudely I agree with you on that that all after hour calls and texts need to be kept strictly professional. Emotional affairs start that way all the time. They look for a prince charming to validate them and tell them he treated you terribly you don't deserve that. That's just a level of emotional intimacy OP should not invite into her marriage or her relationship.

Yes they talk about other things maybe at work but for some other woman to be calling/texting an engaged man after work hours are over to discuss non work related matters is not appropriate and shame on her for knowing he is engaged and doing that. Double inappropriate for the fact she is having an intimate type conversation bitching about her romantic life. That's not normal to do to a man about to be married. That's what her girlfriends are for, her family, or better yet a therapist. Not her off limit work colleagues

And the OP as his fiance has every right in the world to tell him not to take any off the clock phone calls or humor her attention seeking need for validation unless it's strictly work related.

Interesting if this was the other way around and some work colleague that was male was blowing up her phone in the evenings after work hours were over to discuss his personal relationship woes with her how her fiance would take it.

Why was he interacting out of work hours with someone he did not like ??
all this blocking nonsense on SM is juvenile

not sure how you overstepped ?
not sure what the achual issue is ?

Personally, I say kudos to him keeping his boundaries and respecting your relationship, but I don't think you've done anything wrong as these actions appear to be of his own volition. I'm a cynical soul and fear that she likely DID have an agenda, so I think he's done the right thing.

She overstepped by calling her male colleague after work hours when he is engaged to be married to bitch about her private relationship matters. It's inappropriate
