Touched a nerve....

I read a list today and two things on it touched a nerve: If a relationship has to be a secret, you shouldn't be in it.
and Everything can change in the blink of an eye. Oh, how true they both are.

I
am currently in a "relationship", that is unknown to everyone but a
select few. Why? He's still married, in the process of divorce, but
still legally, technically married. I was "legally technically" married
when we began this relationship, but I felt it okay to tell a few
people. He's not of the same mind.  So no one  (but a select few) knows
and no one else will know until the divorce is final. But then, he
moves to Korea and will be gone a year...so there's another year that
I'll be alone and miserable. I hate this more and more everyday. I am
just not feeling being in a relationship anymore.I'm losing sight of
myself again.It like I jumped right from a wife..to His girl and didn't
stop to find myself in between...and then no one but you (and work
people) and his parents know about it..and I hate that. I have a
sincere need to be acknowledged.

So, my problem is--How
do I tell him that? I don't want to stop seeing him completely, I just
want to have time to myself and maybe explore the possibility of seeing
other people (no one in particular).
