<human>: Hi reddit, I never thought i'd have to use this sub but here i am.

I've been with my fiance (lets call her Rose) for 8 years now and thankfully this post isn't about our relationship.. but it sort of is.

Basically 3 years ago, one of her close friends (Jane) found one of my closest friend (Ned) cute and so me and rose played match maker and now they're a couple.  I liked Jane at first, I thought she was very cool and everybody finds her pretty, its literally the only thing i hear about her and my friend Ned is a very good looking guy. 

The problem is recently, Rose told me how Jane is thinking of breaking up, Jane said "She feels like they don't connect, theyre two different people and the only thing that got them together was the physical attraction". Rose told me to keep to it myself and she made me promise not to tell before she told me.

See over the recent months, I've started to dislike Jane and I don't like the way she makes my friend feel, I feel like shes just bad for him but he's madly in love with her, so I keep my opinion of Jane to myself.  She doesn't know if she wants to break up with Ned, one day she doesn't the next day she does.. and I've known for a while. 

Yesterday, Ned told me he was planning on proposing to Jane and splashing out a lot on a  ring.. He was planning to use the money his mother left him after she passed and thats when i opened my big mouth and told him not to.. and explained how Jane keeps going on about how shes not sure if she wants to break up with Ned etc.

He confronted her and he broke it off, and now shes crying to Rose about how she realized she wants him now. *sighs*

Now my fiance Rose isn't speaking with me because I broke her trust.

Can you give me the gist of the text in a nutshell?
<bot>: Fiance mad at me for breaking promise and telling my friend who was about to propose to her friend that her friend was planning on breaking up with him.
