It's a long one so bare with me...
A couple of years ago I got close with a friend and with us having DC similar ages and living fairly close we became really good friends seeing each other several times a week.
Since I got close with her I realised her relationship with her partner was terrible. Very controlling and alot of financial abuse. He doesn't help her with the children much and she's expected to stay in the house otherwise she gets accused of flirting. She couldn't even come to my house for a cuppa without him accusing her of there being men here (I have 3 DC and a DH so why there would be men here I don't know)
I've tried gently over the last couple of years to tell her how bad his behavior is and that it's abusive. She knows this but stays.
Recently things got really bad and it opened my eyes a lot to what she's been going through and how bad it is. I'd say on average they fall out 1-2 times a month and it will last 3-4 days then around once a year she will say she's leaving pack a bag etc and go but only to return after a couple of weeks.
This time it went on for 4 months and I was SHOCKED by his behaviour. He is awful so abusive and controlling (I'm talking listening Devices around the house and following her) the abuse even reached me when he started to message me telling me to back off and all sorts of other nasty things (he's already isolated her from most friends and family). She would come round and tell me and DH the latest abuse he was putting her through and my DH was gobsmacked and both of us offered all of our support and help with the kids and also any financial support she may need.
She got so close, but as I predicted just as she was about to go for good this time (house up for sale etc) he's promised to change etc. he suffers from very bad mental health and everyone knows he won't change. I've already seen this chain of events a few times.
The problem is I don't want my friendship to be based around 3-4 months of her ringing crying everyday and me trying to help her for her only to go back.
Il no longer go to their home and have said I won't speak to him again after the drama he tried to bring to me and DH as he's clearly a very unhinged person who quite honestly scares me a bit (I'm not aware of any physical abuse but he is a loose cannon and very aggressive)
Do I massively cool this off and take a step back? I can't believe I've been worried sick for months using all my free time to try and help her get her life together for her to go back when she knows full well nothing will change.
I also hope I do not sound unsympathetic here I know it's an awful position for her to be in and I feel so sad she's going back to it but you can only help so much? I won't spend the next month listening to her talking about how great he is until it all starts again.
So AIBU to back away from this friendship, I will always be there for her but I can't commit to a friendship that is so heavily controlled by her partner when I know exactly what he is like.
