I can really sympathise. my ex is still acting a tosser even though we have been split up 2 and a half years.
At the moment aged 29 he is living with his 19 year old girlfriend at her mums and refuses to have the kids to stay. His mum kicked him out because of his tosserish ways.
Now he is on speaking terms with his mum (she sometimes has the kids overnight although its rare)she finds it hard to cope with two kids and has asked for his help in putting his kids to bed but he always refuses saying he is too busy ie he takes his bimbobitch for meals out, clubbing etc
As a result he hasn't put his kids to bed for a year or had them overnight at all.
He gets himself a good job in a factory, working 4 on and 4 off, fair enough but it has completely buggered up my job as he can't have the kids and his gf wont help because and i quote 'why should I, they are not mine and i've got a life'
He hasn't paid me maintenance for four months because he 'has no money' yet he just bought himself a brand new yamaha motorbike with the house sale proceeds. Mine went on paying off all the debt he left me on when he ran off with bimbo bitch over 2 and a half years ago. He's also taking above bimbo away for the weekend without telling me so I've now got to find childcare for that weekend (dp is on nights and isn't living with me at mo)
He accuses me of being unable to find a house to live because of bad credit rating which he blamed me for!! later admits its not me but him.
unfortunately kids think the world of him and its not my place to fill them in. Hopefully one day they will find out for themselves.
Janos I think you'll maybe feel irritation with your ex for a long time. I hate mine with a passion now but still feel sad now and again as he used to be lovely. I just privately call his g/f bimbobitch and for some reason makes me feel better
