I am posting here because I really don't want answers of 'stop them seeing their father' which is what has happened when I have posted elsewhere in the past. It may be the only solution but perhaps this forum can give me another perspective. Apologies for long post.
Long story short, divorced 10 years following ex's long affair (years) with OW. OW now long gone and there have been a number of women in the interim - ex is one of those who does long relationships, 'love bombing', reels you in and then reveals his true self when he's confident you're over-invested in him. He's never willingly paid any maintenance - got to the point of having his house sold by the CSA and he has had a £0 assessment with the CSA/CMS for 5 years now. Thriving business, just avoids paying tax, lots of cash in hand. Seasoned liar - wouldn't know the truth if it slapped him in the face. Tried to gain residence of the children in the early stages and he is the only man I have ever known had a CAFCASS Officer recommend a reduction in contact (we were pretty much 50/50 but it was reduced to every other weekend and one night in the week). Hates me with a passion - I think I was supposed to commit suicide when he left and he really doesn't seem to understand how it might be that I have coped without him in my life perfectly well. That I am coping, happy, with friends etc. etc. seems to be the source of all his anger.
Our children have endured hearing all sorts of lies and rubbish about me over the years. We are now of an age when the mist has cleared and it is obvious to 2 out of 3 children just exactly what their dad is like. Eldest pragmatic and tries to keep the peace by nodding and agreeing. Middle child desperate for dad to love him so more nodding and agreeing. Youngest child not quite getting it but doesn't understand why dad hates me so much - and it is clear to him that he hates me. I try to be nonchalant, upbeat and gloss over it. I don't bad mouth the ex, we have a perfectly acceptable quality of life on my money alone and we manage. Contact happens, I am a good ex from a new partner's point of view as I am utterly disengaged and distant from my ex, contact is never interfered with (very strict schedule, we know where we stand with it), I never demand money or extra money or any help or support or anything else.
Most recent partner been around 4 years. She has swallowed the line that I am an evil, grasping ex and is abusive towards my children as a result. We have never met. Over the last 18 months, they have become more and more distressed following time with dad, angry at what has been said about me, and angry that dad has such a tight reign on them - won't take them to parties, won't allow them to have friends over, moans if they want to go on their tech, moans if they leave the tech alone and ask him to do something with them...you get the idea. The girlfriend is at the centre of it all - comments like 'I bet that bitch of a mother told you to say that', 'she's a fat, lazy cow' are said at every contact. It came to a head some months ago and she told my children to leave 'her' house (it is my ex's home, all paid for) and my ex finally told her to go.
She went. Only it was clear that she only left the house and their relationship continued. She visited on Xmas Day for example. Children have now been told that their dad loves her, they want to get back together and that she'll change. Middle child keeps repeating adult comments such as 'she's been part of my family for 4 years and I miss her', the eldest is angry and is set to tackle dad about it and the youngest is bursting into tears at the drop of a hat because he hates her and doesn't want to see her and knows that he's not really old enough to make a choice. I have suggested court - saying that I believe if he tells the judge what he's told me, they would more say that dad could have contact but away from the new girlfriend but he is worried 'he's my dad, he'll hate me if I take him to court'. Eldest has promised him that he will go to dad's as long as the youngest also has to go and middle one, despite the 'she has been part of my family' comments is insistent he wont' be going as long as she's there. I should also say that in the last 12 months, he has refused to go on a few ocassions in what has been an attempt to get his dad to listen to him - all failed from an outsiders point of view but he seems to feel happy he's made his point to his dad.
So what do I do? I want my children to have a relationship with their dad. They want a quiet, hassle-free relationship with their dad and are happy for him to be in a relationship as long as that relationship doesn't involve slagging me off constantly. I am powerless to stop mid-week contact for the youngest because I work 15 miles away and can't be there. School will hand him over as they have no reason not to. Other two are in secondary and can make a fuss at the gate if needed, although I suspect would go with him if it came down to it. We can control weekend contact because they are picked up from my house so they feel stronger in saying 'I'm not going' because I'm there to support them. He wont' mediate - have tried for 10 years to get him into mediation but he won't do it (I assume because he knows he's utterly in the wrong on most things and would prefer not to face that). My children are stressed, upset and about to lose their father - I feel I might as well have played the alienation game (because lord knows, I had good reason to) and I just don't know what to do to help them.
