I have 3 beautiful children, 8 7 and 2 years old. My wife and I split about 3 months ago and I can't stand the filth she has my kids living in. Every time I have the kids she goes to the pub and gets trashed, leaves her car there then relies on others to get the car back the next day, but because she's hungover she swears and can't be bothered with the kids. Bottom line is, I think she's a bad mother and want custody of children. Just wondering if her cheating on me in our bed, in our home is grounds for being an unfit mother or faking getting a permanent contraceptive rod put in her arm so that I would stop using protection and have another kid or even putting pins through my condoms to get pregnant is grounds in family law for being an unfit mother.
