Potted history - Split up almost 11 years ago when kids were wee - Girls now 12 & 15.
Ended relationship due to his inability to take responsibility for himself. I became his mum, essentially... Shortly after splitting, he lost his job and he hasn't paid any maintenance since. Made a right song and dance about me finding new partner (dedicated step dad who financially co-supports them with me for almost 10 years) and he has been a feckin nightmare on and off ever since - mostly verbal ranting (mainly emails) and being difficult about taking girls, not co-parenting, not seeing girls on and off because he was 'depressed' or 'too poor' (whilst going on 2 week foreign holidays and maintaining a smoking habit). Series of girlfriends but none have stuck. Series of mental health issues -he mentioned bipolar once but not sure if that's official - defo clinical depression, but I suspect a personality disorder, and physical health problems (COPD due to smoking).
Regardless, I've always tried to promote his relationship with the girls, mainly because they were blind to his flaws and enjoyed the time they spent together. He's always tried to engage with them as a friend, rather than a dad - eg cringy text conversations that start 'yo girlfriend!' and complete lack of structure/discipline and I always wondered if their feelings about him might change as they grew up and took a bit more notice.
Fast fwd to last year or so, when they gradually became less keen on seeing him/spending time with him. My eldest (15) has been particularly reluctant to see him and my youngest is catching up fast.
This Christmas it was his turn to have them so we made the usual arrangements, encouraging the girls to keep their commitment as they were making reluctant noises... Christmas day we made an agreement for them to tell me when they were opening their pressies so I could call afterwards but they never called and I was getting worried, texting them and calling etc. Eventually I got a one-line response from my youngest saying 'please come and get us mum - quickly'.
I tried responding, asking what had happened - all whilst putting shoes on and getting into the car as the text really worried me - the tone of it was so strange and it was completely unexpected. Nothing like this had ever happened before. It's also a 30min drive so I was worried something serious was unfolding. Ex has never been violent to girls in any way but there was an isolated incident with me towards end of our relationship and I just generally don't trust him - he's unpredictable and emotionally very up and down. He also took the girls away overnight without telling me a few years ago, triggering a police hunt across the bloody country. He hadn't seen the girls for months before that because he was suicidal so I genuinely thought he'd lost it.
My partner communicated with her all the way there as she was too upset to answer the phone/speak. She wouldn't tell us what had caused this though, just that she was too upset/crying too much to talk and that my eldest was packing and trying to calm their dad. With that, we called the police to explain and they agreed it warranted a visit. I asked them to meet us there in case I couldn't get access (partner didn't want to add flames by storming in) but as it turned out, the girls came out themselves - they were pretty hysterical, looked exhausted and didn't want to talk about it. We didn't push them, gave them as good a xmas day as possible then talked the next day - turns out he had had a meltdown because the girls 'didn't like him anymore' - he told them to go back to their 'real home' and kept flipping from telling them 'you're all that I've got' to 'why are you not more upset?'
Basic emotional blackmail - trying to gaslight them into a response to justify his victim mentality. He did it to me all the time.
Turns out, after much talking, they've been picking up on his emotional manipulation for a while - he also bad mouths me apparently then is fake-nice to my face (obvs I knew his real feelings, but I thought they were buying his act), and they feel really uncomfortable with it all - they want him to be a dad, not someone who tells them all about his problems then manipulates them into feeling responsible when he's upset. Basically, they can finally smell his bullshit and he's thrown his toys out of the pram.
They've asked for space and no contact but he's pushing for mediation/resolution - saying he can't sort it out if he can't contact them. He's now arranged family mediation and has asked me to pay half!! Girls are reluctant but they agree they'll have to talk to him at some point - he's a dark cloud at this point and it's increasingly hard to ignore him.
I'm going to arrange counselling for the girls anyway, to help them vocalise their feelings and hopefully feel more confident about voicing their opinions. I think he expects a quick chat then they'll start visiting him again. Meanwhile, I can't imagine trusting him enough for that ever to happen....
