I thought ex MIL and I got on ok and we'd reached a point of understanding. However, something has been said and now I'm being ignored (messages and phone calls). I want to know why but I don't want to push my luck. It's upsetting me because I do care about them and I also want to know what it is that has caused the sudden change. But I don't want to harass her. I don't really know what to do.
