How can I help my best friend out of a abusive relationship?

Trigger warning

My best friend has been in a relationship with her abusive boyfriend for almost 9 months now I only found out about the abuse 3/4 months ago and I’ve sat patiently and quietly supporting her trying to end the relationship helping her find ways to get out of the relationship, get him to leave her flat etc and then she dropped the bomb ironically just after midnight on New Year’s eve that she wants to try making the relationship work, this guy has hit her, raped her, mentally and financially abused her and I frankly feel like she’s wanting to stay because she doesn’t want the heartache and pain of a breakup.

She apparently has 2 different counsellors that she sees one for her normal mental health and one for domestic violence, now I don’t know if she actually does have this support I’ve never seen any evidence or even a text from them and I don’t see where she would find the time to have her online sessions with them as she works 12 hour shifts, but if she does actually see these people I don’t believe she is telling them the full extent of what is happening because apparently both counsellors stance is that whatever she is wanting to do they will support which to me seems like they shouldn’t be in their career because their sole job role is to help people not encourage damaging behaviour and circumstances, I also highly can’t see them agreeing that it’s good to stay in the relationship as she has a 3 year old child (not his) which being exposed to this type of abuse can be extremely difficult for her to live with.

I can’t just cut her off or let her live and make her mistakes because I’ve done that already during her relationship with him and things always go bad, I’ve offered so many ways to help her like getting the police, getting my boyfriend to help remove him from her property, getting her help from a domestic violence service all of which she refuses.

I understand that this is her decision but I can’t sit by and watch her suffer in this relationship anymore no matter how many times he says he’ll change and then he goes back to the same stuff.

This relationship is taking a negative impact on her mental health and her other relationships like with her family and mostly me, he starts arguments when she wants to hangout for long periods of time, I can’t hangout with her unless I’m bringing her to work or home from work because because I refuse to be around him at her house because of his behaviour that’s something I don’t wish to expose myself too, we can’t go to mine because I live with my parents and we’d be stuck in my tiny bedroom and if we do hangout when he’s at work I have to come over at 7pm and leave by 7am

I just don’t know what to do if I physically can’t sit by quietly and let her do this to herself after removing herself from her abusive childhood home to then just over a year later put herself back into an abusive situation

Any advice on how I can support her on this would be greatly appreciated or even support services I could contact
