Sounds like they want to break up but don't really have the guts to.

I'd dump them and say "Have a nice quackaroo life!"

Quack.

Sounds to me like Duckie is right. He wants to "test the waters" to see if there is anything else out there. If he's a big loser and nobody else wants him, then he'll keep you around. But the minute he finds a "better replacement" you're history. 

nods. Plucks out feather. Tries to tickle your toes to see if your senses to such wisdom awakens...

well if its a dude he feeling confident ,probably getting some offers(because chicks always want to sleep with a guy with a girlfriend) and want to get as much as he can. if its a chick shes probably done but dosent want to be alone, ie she wants to find a good lay before she dumps him

Treat your relationship like a newborn child.  At the beginning, love is so bliss.  You are excited to see it come out in this world, you feel the love so deep, you want to do everything to make it right, you want to take care, understand, you will do anything to for that love (baby).  As the years progress, that baby is now 2 years old.  It is a toddler now, the terrible 2's.  You still care for that baby, nothing has change other than you are beginning to understand the baby more by their needs and wants.  You still have a long way to go to raise that child a good adult.  At 2, your better half wants an open relationship.  He wants to stay true to you but wants others too.  Love is a committment and if neglected at anyway, who knows where it will lead.  That's where majority of the divorce occurs here in the state.  We tend to forget that to make it work, it isn't you and I but us for life.  Love will be test and it will not be easy for many.  But as you look at the emotions that flows from the old couple you see everywhere you go, you often wonder how they made it work.  I asked a few times from the old couples that I have seen on what worked for them to have such love going.  Majority of the response I get is that love is about us.  If you figure that out, you can go through life happy.  And don't get me wrong, love will be test.  And many will fail.  They say us as a response cause that love takes a lot of work.  For it to work, there has to be two involve in compromising, understanding, making the decisions, caring, loving, etc...  If you try to work on a relationship on your own, it is tough to keep that relationship together as you are the one always trying to fix it.  Like I said before, treat your relationship like a child.  As we were once kids ourselves, we know the love that we get from our parents.  Any neglect, we can feel it.  If you lack care and love, we know.  Love knows if you stop all the right emotions for it.  Just my thoughts.

First, if you're serious with her there is no way that its going to work, in my opinion. It takes two to tango, always... not three, four or.... You'll end up hurting one another. If it's not a serious relationship then it's fine. There is always emotions involve in relationships serious or not. What's the most important here is what you BOTH feel.
