I'm sorry you had to get through these experiences. There are plenty of stories on here that talk about issues with in-laws and it seems it's a universal theme of discontent, so trust me, you aren't alone in that. Many are even less tolerable, not to compare of course. It's probably for the best that you and your wife spend some time apart from them. Of course, if it gets worse or trouble with them increases, you or your wife would be best to tell them that if they don't stop with inflammatory comments, and offence against you, you will have to take a longer break from them. That will force them to reconsider their behaviour against you.
