What to say to a guy when he tells you to call him?

Answer 1

Just say "ok see you later"

But first make sure you have his number... if you don't have his number, give him a sticky note and say "write it down."

Answer 2

You can respond by saying "Sure, I'll give you a call", or "Sounds good, I'll reach out to you soon." This shows that you are open to connecting with him.
