Oh, don't mistake.
That is purely n=1 for THIS relationship.
I've been in short relationships that I've ditched.
I've been in alternative relationships that were plural.
I've lived the hooking up with a different girl, or two, "every night is a crazy party" life.
I don't believe in the 'there is only one way to do it' moralistic version that is sold AT ALL.
I just happen to be extremely happily monogamous right now.
And in all likelihood for all of the foreseeable future as well... baring something happening to my current partner that forces a change.
