NC as this is outing.
Have a friend who I've known around 10 years. Met my lovely dp through her. Before me & dp got together she couldn't praise him enough, lovely guy etc.
Few months after me & dp getting together, things changed regarding friends attitude towards my dp.
Started making up small lies, telling me things dp had been doing or saying that I could prove weren't true. I let this slide without having the big confrontation etc but did flag a few things up to her.
Several things have happened since then, she denies all knowledge.
It has became clear that she hates my dp, she still continues to make up these lies etc and is so nice and caring etc to my face, even regarding dp! Acts how a real friend would act.
It's all little silly lies but lies that could cause a lot of trouble between me & dp.
Nothing regarding cheating etc but still lies that could lead to us arguing.
Please note these lies she has told, are all lies, it's not a case of me not wanting to believe it etc, it is proven lies!
I've mentioned to her a few times about things that she's said & she then just avoids what I have said regarding the lies or dp.
I haven't exclusively said, "I know you told this lie" but I have left her know that the lie she has told, I am aware it's a lie, as I say she avoids it.
What do I do? Where do I go from here?
Do I just totally call her out on her bullshit? Or do I leave it & make note of all these incidents?
