Too much Mercury is at work; you
think into a relationship.
I am not saying that such consideration shouldn't be taken into
account, rather, when you start telling yourself that age is
catching up on you and probably should begin some kind of
relationship, it is but society's influence AND biological pressure
on you to began a BGR in order to start a family. Not exactly that
of Love.
We all Love from different degree: how much self actualization you
would gain from your relationship depends on which angle you desire
to look at and attain. In simple tongue, you WOULDN'T mind trying
her out, but is Love really involved? You probably need to do a
little self discovery here - you begin to reciprocate remarks that
you may not really mean it (or as much): e.g. I like you. Such self
dishonesty and delusion will definite add volumes to your confusion
and spew more issues as time goes by.
In fact, you are confused because you wonder if you should try her
or not - not exactly whether you Love her or not. Like you have
questioned yourself: are we merely friends material or is it
possible to bring that level higher? IMHO, if a someone don't
really fit into the critical frame of your what you want, chances
are without substantial Love, it could be karmic
relationship.
Companionship or Relationship? You could do a little more inner
searching here. 
Cheers
