请帮我看看这篇短文有没有不对之处
Ted was a wealthy,lonely widower who had two children,Jack and Kay,both living away from home.One day,Ted met a young woman named Yvonne and soon bought her an engagement ring.
Due to the age difference and Yvonne’s suspicious overspending,Jack determined to find out everything about Yvonne.He unexpectedly found Yvonne had five engagement rings.When Jack told Ted that Yvonne was a defrauder,Ted was hurt and told them the other explanation.
尤其是那句suspicious overspending我是想表达她花得比赚得多 很可疑
