Question

“一直以来给您添麻烦了”如何表达才委婉而又符合英文表达习惯

我写的是 excuse me for all the trouble I have brought to you

但我觉得有些不符合英文表达习惯，也显的太见外了，对方还是比较熟悉的，只是想表达的礼貌一点

Answer 1

I am sorry to have brought you so much trouble.

Answer 2

i am sorry for having troubled you for so long a time

Answer 3

Sorry for bothering you.
