@boodle, thank you for the reply. Don't worry about being blunt, I'm never going to snap at anybody here even if it's something I don't want to hear necessarily.
In regard to Facebook, I've already unfollowed her, I only saw the post because I checked my friend had said happy birthday. Odd tangent, she used to have a false birthday on FB and I forgot if I told my friend that actually no, this was the actual date. Either way, yes, she's unfollowed so we're still friends but I don't get anything she posts etc. She wasn't amused by what he posted, which she stated without me prompting it.
Yesterday we spoke a bit about "us", only for him to emerge forcing her to hide her phone, because he wants to read our conversations, it made her pretty angry, she feels its disrespectful of her privacy. I suspect the simple answer is he's jealous of me and feels threatened because of who I am/was, he clearly has feelings for her so I'm very much an inconvenience.
In terms of my gut? It's tricky, I'm default a massive pessimist, I will always convince myself of the single worst possibility, it's a bizarre protection technique I think, just prepare for and accept the worse case scenario so "I'm ready for it". Of course, it doesn't help, I just feel awful and get to say "told you do, never goes right". I find negatives and find ways to confirm them to myself, it's such a self destructive character trait. In my happier moments, it subsides and I just trust people at their word, but of course it's not been a happy time.
In terms of distance... well, she raised this before a few weeks ago before we fell out and stopped speaking when I decided to just give her space, it is since giving her that distance that she herself appears to have come to the conclusion that the behaviour is concerning and she is demonstrating a clear repeated dislike for it. I see what you're saying about potentially enabling her, right now? I don't really give her any advice (my advice would be to get the hell away from him), I just let her vent and listen. If she starts to begin to forgive the behaviour again and making up excuses like she did originally? I will distance myself from the topic, I'm not interested in playing the "he's so nice game."
He isn't, he's an abusive, possessive, controlling narcissist, so I'm not going to allow her to just vent and then go back to la la land where he's really "nice".
In terms of the fall out, it happened before she really got to know him, but I firmly believe they got closer because of it. She often refers to him as "her only ally down there", so I think the biggest allure to him is that without him, she'd have nobody. I suspect he probably knows that on some level, pretty easy to control somebody desperate for company, he's very jealous when she talks to anybody else.
You're right of course, I do have to look after myself... there is an irony that she said it's about time I focused on myself too because I always neglect myself. I haven't for a long time, I always try to help others and it's at my expense, constantly. I get your point that if I want to be a supportive friend and I allow myself to crumble than I can't be that anyway. I'm already in a depressive rut and unwell.
Now that it is clear that for the moment all we are is friends, it'll probably be easier to distance myself from it. Yeah, I don't want her to get hurt but this is her battle. She has stated I am still the most important person in her life, it's nice but... that can always change. I won't abandon her unless it's pertinent to do so but yeah, I'll just have to listen when she needs to vent and let her come to terms that this is a toxic friendship that isn't going to enable her recovery.
She's come a long way, but keeps bringing up how he makes her feel like she's not accomplished anything. Hopefully she realises that if she was brave enough to break up with me for the sake of her recovery being put first that she needs to be brave enough to stand up to and cut out somebody who is actively working against her recovery.
But that's her battle.
