extended family

I'm a little stuck... Click here to teach me more about this clue!

'loved ones and relatives' is the definition.
I can't judge whether this definition defines the answer.

'former nurse unfortunately failed my' is the wordplay.
'former' becomes 'ex' (prefix meaning former or onetime).
'nurse' becomes 'tend' (tend can mean to nurse or look after).
'unfortunately' indicates anagramming the letters (a bad or unfortunate spelling).
'failed'+'my'='failedmy'
'failedmy' is an anagram of 'edfamily'.
'ex'+'tend'+'edfamily'='EXTENDED FAMILY'

Can you help me to learn more?

(Another definition for extended family that I've seen is " relations".)

I've seen this clue in The Times.
