I never needed the legal route, luckily. We don't even use the CSA. When we split, I told her in no uncertain terms I expected her to behave appropriately as regards the children and i'd make sure that they never went without, would always be there when I said I would and I over-pay maintenance every month, on time. I went on to explain if she fucked me about like you see all-too-much i'd put her in the ground and they'd never find the body.
I prefer to think that common sense prevailed, rather than the threat scared her into compliance. We have spent every xmas and birthday since we split in Oct 2010 together as a "family" for the benefit of the kids, this year was the last year as the kids are old enough now (10 & 8 ) to understand. We had xmas dinner at her house, me, her, the kids and her OH. He seems like a decent bloke and the kids like him. We behaved like adults, it wasn't uncomfortable. As a thankyou for having me i've sent them out for dinner together on me, when I have the kids. The biggest issue was explaining to my GF where I was going for xmas lunch lol, but she's accepted it.
Thread hijack! lol!
