I am an only child. My husband has an older brother who is married with two primary aged kids. We live around an eight hour trip apart and my elderly FIL lives closer to us. My SIL can be difficult to get along with and is self centred. I have discovered that they are on a uk holiday closer to us but clearly have no intention of visiting. Should i tell my husband or should i keep quiet. All of this feels like part of a plan to distance kids/BIL from his family. Should i let my husband know or keep schtum?
