Her boyfriend went steady with her.她和男友感情稳定。Go steady指“感情稳定”。

英文单词steady 是“稳定、不摇不摆”的意思。至于go steady，则是形容男女双方的感情稳定。
若一对情侣已有固定的约会，关系稳定下来后，便可用这成语去形容双方感情的状况。来看一个例子：As they have gone steady for years, they decided to get married at the end of his year.由于他们多年来的感情相当稳定，所以他们决定于年底结婚。
我相信，所有的年轻人都希望听到下面的话：“I want to go steady with you. Do you want to marry me? ”（我希望我们的感情能稳定地发展，你愿意嫁给我吗？）有固定的约会，情侣的感情自然就会稳定下来。
date是约会的意思，而regular date 就是指“固定的约会”。例如：They have regular date and they develop a firm relationship.他们有固定的约会，关系亦已稳定下来了。
