My grandma has left my grandad.
Biologically she isn't my grandma but they've been together since before I was born so she has always been my grandma, she still send us cards, keeps in touch etc, grandad doesn't, it's obvious grandma has always done this, not grandad.
My dad, who doesn't get in with her because she was the OW and grandad who's not takin the split well think I should now cut her out of my life because "she isn't really related to us"
But she is to me and my 4 children
