@Feek whoever the poor guy is, he has my sympathy. This is hell, I know.
The truth is most stories go similar to
@Le Clandestin Brun and mine. The family courts, cafcass and social services are all heavily biased in favour of the mother. It's really quite sickening.
It's been almost exactly 10 years since I left the ex and she's still constantly causing problems wherever she can. My current situation regarding this is not easy. She managed to alienate my son from me completely. The stuff he says and believes about me never took place and doesn't even make sense but he refuses to be in my life. He's had me interviewed under caution, twice because of false accusations encouraged by his mother.
My eldest daughter spends 60% of her time with me, and that's despite evidence of her Mother and brother being violent towards her and constant bullying to try and turn her against me. The poor kid is a mess but my hands are tied with a court order and unless she comes home with bruises I'm court ordered to send her back each week. I've tried everything to help her.
I should have taken them with me when I left but that evil **** had me utterly convinced I had no rights to my own children.
Do I regret leaving though, not at all. I put up with years of emotional, psychological and physical abuse because I didn't want to leave my kids. Had I stayed any longer I believe very strongly I'd of ended up taking my own life. I came very close, even had a plan I tried acting on.
I couldn't imagine not seeing them everyday but I realised my continuing presence in that household was worse. They were seeing what was going on, seeing me suicidal and broken. It took me about 6 months to see them again and there's been periods of a year or more where I've been falsely accused and not been able to see them. The point is though despite everything I keep fighting for them and my daughter knows it you'll be surprised at what you can get used to for your kids.
I promise you they pick up on your unhappiness and arguments with your wife etc. If there's absolutely no chance of reconciliation (I don't know your circumstances) then you need to split as amicably as possible and above all else get yourself the best family solicitor you can find.
