enter into engagement with meaning in Chinese

In short , my dear aunt , i should be very sorry to be the means of making any of you unhappy ; but since we see every day that where there is affection , young people are seldom withheld by immediate want of fortune from entering into engagements with each other , how can i promise to be wiser than so many of my fellow creatures if i am tempted , or how am i even to know that it would be wisdom to resist
亲爱的舅母，总而言之，我决不愿意叫你们任何人为了我而不快活不过，青年人一旦爱上了什么人，决不会因为暂时没有钱就肯撒手。要是我也给人家打动了心，我又怎能免俗？甚至我又怎么知道拒绝他是不是上策？
