MIL lives about 8 hours away from us - she retired to the area she lives in when DH went to uni, it’s not that he’s moved away from the family home. We used to live 3 hours away from her, but after living overseas for 2 years have settled in a new area of the UK. FIL died 2 years ago so it’s just her.
MIL is in her late 70s & coping okay on her own, she has a good social life where she is but says she feels lonely at weekends.
