I have a 13 yr old nephew and his mom and him do not get along.His mother is very mean to him putting him down all the time.Well he got tired of it and decided he rather live with his dad he told his mom and she got really upset and kicked him out.He called me and i took him in until his father can pick him up.So his dad took him but he brought him back saying he cant afford to take care of him and hell come back for him when has more money.His mom called me telling me that she wants him to stay with me for a year cause she cant handle him.But now she wants him to come back but he doesnt want to go back b/c shes so mean.So i was wondering how old does he have to be to decide where he can live?Im his aunt so can he choose to stay with me and be his guardian?
