My XH picks my DS from my house. It was the marital home but I bought him out, so its all mine now. When he collects DS he comes in and sits down whilst I sort DS out with shoes etc. Today I could clearly see him looking round the dining room whilst I was putting DS' shoes on. I called XH into the hall and asked him what he'd been doing. He said he was just sitting on a chair! I told him he wasn't I saw him.
He also just goes to the bathroom/DS' room without saying where he's going. He basically treats it as if its his house. Aargh he drives me mad.
He also pays no maintenance and if I ask he says he has no money - he claims job seekers although I suspect he is working too. I'm going to ask him when he brings DS back what he's doing about Jan money, and if he says nothing then I'll be telling him I'm contacting the CSA.
Sorry, needed to rant a bit plus I'm pre-menstrual!
