我同意kaly "老生常谈",or "陈词滥调"
by the context , I guess, what you told her was that maybe you have told her for hundred times ,so it sound like a cliche and she was tired of listening to you. is that right?
in that case, I think a Chinese four-word-phrase "老生常谈"/"陈词滥调" will be the best expression for it.
sample :
他的话就是老生常谈,没有点新鲜玩意儿,大家都听烦了。
