Why don't you like him, why don't you want him around your son? Honestly, I think it's horrible to keep half brothers from each other. Whether you like him or not, he is still your son's brother, and your son has the right to know him and decide for himself (when he is old enough) if he wants a relationship with his brother. If he has legit problems that concern you, then you need to address them with his father, and encourage him/them to seek help if it's needed. But, in all honesty, if I was with someone and they told me they didn't want my kids around a kid we had together, that would be the end of the relationship. So, you really need to decide if keeping your son's brother away from him is worth potentially keeping his own father away from him?
