After all, I have a nice, (no first person) association (8)
I believe the answer is:
alliance
'association' is the definition.
(I've seen this before)
'after all i have a nice no first person' is the wordplay.
'after' means one lot of letters go next to another.
'have' says to put letters next to each other.
'no' suggests deleting specific letters.
'first person' becomes 'I' (first-person pronoun).
'nice' with 'i' taken away is 'nce'.
'all' next to 'i' is 'alli'.
'alli'+'a'+'nce'='ALLIANCE'
(Other definitions for alliance that I've seen before include "Coalition or union" , "match?" , "Bond" , "Formal agreement" , "Union, association" .)
