H visited his family on the weekend and S visited them as well. S says that H doesn't quite fit in as well there anymore, particularly with the extended family. He says that H's sister did not come to the family lunch but called in afterwards with her family. S says she greeted H but avoided him for the rest of the time they were visiting. How interesting that SIL continues to ignore H and that MIL 'allows' this but had to challenge me and say she thought I was too harsh on H.
