Do you consider exchanging numbers while in a relationship as cheating?

My girlfriend says its cheating but I tell her I will not go to cheat on her with them its just just exchanging numbers and some texts.
And I don't do it when I'm out with her but only when I'm out with my guy friends its kind of fun for us.
Its cheating
Its not
