Pretty close, and perfectly understandable, but some tweaks: ...The first years of their marriage were *very* happy... ...She asked him what the reason for this was, Bob continued coming home drunk almost every day, and Beth became more and more apprehensive. The couple's peace was lost, and their arguments were constant. Depending on what style you want in your writing you might change that last bit further to something like "The harmony that the couple used to know seemed to have been lost forever, and...." I rather like that last clause "..., and their arguments were constant." It's a little unusual in "normal" English but here it has a slightly poetic feel to it. :) Hope that helps

Bob and Beth loved one another and got married. They had dreams, so they planned a life together. The first years of their marriage were happy.but one day, Bob got home drunk, and Beth became concerned/ worried.,so she asked him what the reason was , but Bob didn't answer. Bob continued going home drunk almost every day, and Beth began to feel uncertain of their relationship/ began to feel apprehensive about their lives together. The harmony they shared began to evaporate, and arguments between them constantly happened/and they argued often

Well put! A few corrections. You would say: Bob and Beth loved one another and got married. They had dreams so they planned a life of realizations. The first years of their marriage were very happy. One day, Bob arrived home drunk and Beth became worried. She asked him what was the reason for this, but Bob didn't answer. Bob continued arriving home drunk almost every day, and Beth began to live apprehensively. The peace of the couple disappeared and the arguments were constant.
