I'd check h a lawyer before making a decision like that. In my case it was my second marriage and it was my house so it was a no brainier, she had to go. I moved into another bedroom, filed for divorce then kept asking her if she had found another place yet. Took four long months but she finally found motivation to leave. She wasn't hanging around much back then anyway so all she really had to do was move her stuff out and change her mailing address.
