So for some back story, I’m gonna try to make this as less confusing as possible. 

I have a group of 3 friends and we all work together and live in the same area: 
Let’s call them: 
Chris
Lisa
John


Chris and Lisa are my best mates in the city I live in, but they aren’t close with each other. 

Chris and John are good friends and that’s how I met John

Lisa &amp; John met at work about 8 months ago and began dating about 4 months ago. Since John &amp; Lisa are dating we all go out together and chill. 

Now to the story: 
L talks to me about J allllll the time. She has been looking for other jobs in other cities around Europe but is now considering staying in Germany for J. She also in her 30s so looking to settle down soon. J is 27 and not super interested in that atm. 

About a month ago, J told C that he wants to break up with L but is terrible at these things. C then told me this information. So I have been sitting on this behemoth of a secret while L chats away about planning all this stuff for J. I try to casually slip in that she should really plan things for herself and maybe reevaluate the situation before putting plans on hold for a guy. She is not picking up on it.  Girl to girl, It’s hard to watch her doing this when I know what’s really going to happen. 

Fast forward to last night. We are all out one last time since I got another job and am moving to another city. During this time while L is away, I asked J if he really is going to break up with her, because he should do it sooner rather then later. He says yes, but doesn’t really know how or when etc. he wanted to do it after Christmas, but then she is going back home for a few weeks... etc etc 

The night continues and many drinks later - L and I are outside the bar and she is complaining about J not wanting to make plans in March for a weekend away and other things. I try to tell her that maybe she should call things off since she is not really getting what she needs from this relationship. She says “she loves him” etc and my big mouth just blurts out that he is going to break up with her and she should just end it. 

She shouts at me, I go back inside, she runs to J crying, he looks at me, they walk out. 

I feel like the worlds biggest asshole and also like I am in grade school again. 

I apologised to both of them but feel like a massive idiot and an even worse friend. Neither will speak to me and I have no idea the status of that mess of a relationship. 

Tl;dr - found out a friend wanted to break up with another friend- got drunk and told her that he was gonna do it. Neither are talking to me.
