She [topic-は] happy life [object-を] sent.
生活を送る ('to lead a life') is the standard biographical frame for describing how someone lived their days. The choice between native 幸せ and Sino-Japanese 幸福 colors register and warmth: 幸せな生活 feels gently personal, while 幸福な生活 carries a more elevated, abstract tone. Both are equally idiomatic; the pick often comes down to style and rhythm. 生活を送る remains the natural collocation in either case.
