What does "we should keep in touch" mean?

[Anonymous]

I contacted a guy (not really knowing who exactly he was) recently that I met a few months ago. He remembered me and we had a short text conversation which ended with him saying it was good to hear from me and that we should keep in touch. What does this mean?

In normal terms it means we should contiune to talk and not forget the other exists.
