He didn't act like a true friend this time — couldn't reach him at all when I needed him.
Tips
memory
Literally 'enough friend' — i.e. 'friend enough (to step up).' 够 here means 'measures up to / qualifies as,' so 够朋友 = 'qualifies as a friend (in deed, not just name).'
register
Colloquial and warm. Often paired with 真 (zhēn, 'really') as 真够朋友 to praise someone, or negated as 不够朋友 to call out flaky behavior.
