What do you do when you just don't like their partner ... you can see they're manipulative and have told lies in the past to get what they want. Very controlling.
DC has been told this by family and friends and distanced themselves for a while from the relationship but is now back in the thick of it.
I've backed off as I've said what I think, they're an adult, and I don't want to damage my relationship with them ... however I find it very difficult to sit and have family meals, drinks out etc as though everything is ok.
I dislike very few people, both DH and I are very chilled, try hard to see the best in people, and have welcomed this person into our lives and included them. But there's a line, it's very difficult.
