Live next-door to in-laws, they aren't married but have been together a number of years. Don't have a good relationship with them which is exacerbated by behaviours from him that I don't like, racist remarks, binge drinking, anger management issues &bullying, living in a tip, so I keep completely out of the way & avoid wherever possible. However dd age 18 is very pretty & now he is staring at her obviously, (it may be to intimidate, I don't know as he is such an unpleasant character). Want to keep the peace however I really don't want dd to feel uncomfortable at her own home. Issues in the past have never been resolved well, sil has previously said 'just don't wind him up' .... Any advice?
