・there is something I want to talk about, but
・I have something to tell you, but

「我有話想對你說」可以用英語 there is something I want to talk about, but 或 I have something to tell you, but 來表達。

There is something I want to talk about, but can I have a little time after work?
（我有話想對你說，下班後可以給我點時間嗎？）

I have something to tell you, but is it okay now?
（我有話想對你說，現在方便嗎？）

希望以上有幫到你。
