In a long time / For a long time

Hello Teachers,

Are the following sentences correct?

1. Didn't you meet your daughter in a long time?
2. Haven't you met your daughter in a long time?
3. Haven't you met your daughter for a long time?

If they are all correct, what is the difference between
sentence numbers 2 and 3?

Thank you.

Hello, :hi:

Let's try it this way,

[A] You haven't seen your daughter in a long time, have you?
=> within, inside of a period of time; the length of the period is left open

[B] You haven't seen your daughter for a long time, have you?
=> over a period of time; the length of the period is not left open

Are "meet" and "see" synonymous or not?
It is common among Asian people to say 'nice to meet you again'
whether they meet someone (whom they have been introduced to earlier)
in real life or on the Internet.

Thanks

That's the correct usage.

Nice to meet you. (First time)
Nice to see you. (Second time, third time, and so on)

Exception
Max: Nice to meet you, Sam.
Sam: You, too, Max.
Max: Nice to see you at the convention. (glad you could come)
