"Save" means "to keep and store up (something, especially money) for future use". But I thought this verb is used only with some words(save the day, save money, save time etc.), and doesn't fit in every context, as in
W : "Why don't you tell me that you love me?"
M: "I'm saving it."
It's wrong, right? Here, what I want to write was that,
the man didn't tell her that he loves her yet, because he's waiting for the right time to say it. Or he's trying to find the right way to say it. He's just "verb(which has the meaning of "save")"ing to say "I love you" to her. Maybe he'll say it to her later.
I initially wrote "save" here, but then I thought it's very awkward and I've never seen anything like this usage in English.
What is the proper word to use instead of "save" here? And in what context or situation can I use "save" in English?
