Fustrated

My son is driving me absolutly crazy. Serisouly it makes me want to scream. he's not a bad kid. Really, he's great, in fact I never see him. All he wants to do is be at his friends. I try to limit it, I've told him to stay home and he fights me on it. I just don't think it's right that an 8 year old be running the neighborhood all day and his father thinks it's fine and I don't. If he's home all he does is wine and cry about being board. As soon as he was done breakfast today he wanted to leave right away. I said no, and he started to wine and then I told him to go and just move out since he's never home. Of course, i felt bad about it after I said it but he just drives me crazy. I don't know what else to do. The neighbors are going to think or probably already do that I let my kid run wild. Eric just says "he's a kids , let hime go". But he's not 14, he's only 8.
