We have been battling my husbands parents for 6 years on small issues such as what we allow our children to view on tv or as big as feeding our 2nd oldest things that make her ill ( She has severe food allergies, asthma, severe excema, and a thyroid disorder ).  Over the years we have slowly pulled back letting them stay their unattended by us. To only allowing them to come visit them here.  Until recently they have been nasty to our children in our back yard while we were in the house.  We have been repeatedly torn down by them going against our religious beliefs towards our children, speaking hatefully about us to them and turning around and telling lies to my husband about things my children were doing to them.  Also when confronted on letting my children watch movies with sex scenes in a room alone she denied this after sayingshe did so in the past.  We have tried several sit downs and nothing can be resolved we are accused of raising our children to be liars, getting into her medical files, and allowing others to listen into her phone conversations.  She is upset with my husband for choosing myself over her.  And after a recent sit down she has told me she is through with me and things cant be worked out.  We have decided to wash our hands of the situation after her lying to us repeatedly and not willing to respect our household and wishes with our children.

My question is as a Christian is this the right thing to do?  We have went to them on numerous occasions trying to patch things up but they still act the same way.  Whats a mamma to do?
