My in laws are the first people to moan if we don't see them but the last people to ask how our children are.
If I message my mother in law updates or exciting things our children are doing I might get a smiley face emoji or a "that looks good" if I'm lucky. If I message asking about them I'll get a long reply of how they are but rarely a "and how are you?"
I just feel like giving up but as the daughter in law I know it will be seen as all my fault.
