For a moment, I thought you are someone I
might know. If I guess correctly, my phone is always open to you.
Don't bother asking who I am, by this nick, if you know, you should
know. If not, definitely wrong number liao.
Clue to the above claim: If your gf is Aries.

Your relationship has hidden and obvious issue you have to work
through - it basically needs clarification, understanding, empathy,
strength and lastly structure, to ensure growth and stability of
your love.
Understand one thing - everyone is different in their own ways.
Your girl is not the usual kind of woman you are dating - infact,
roles have changed. She upholding mascline energy of the
relationship, while you supporting the feminine energy. She is cool
in her behavior, dislike emotional talk and is secured with
preception of trust in relationship - You are the direct opposite.
Jealousy slips in heavily because they are gaps within your
insecurity.
Lesson one:
Learn to see her as herself and NOT as a woman.
The dynamic of her personality is different and this leaves much
room for exploration. She is like a block of ice - she says she is
'like that want' because previous relationship did not break up
this rigid emotional ice block she has constructed and crystalized
over the years.
Psychologically, it could be her early childhood and
environment that influence her.
Your job in lesson one is to keep knowing her better as a girfriend
(No, you don't know her very well still) and to soften her up. Chip
and break up the block of ice into cubes so that it is easier to
handle. She can't be like what you are - possible clingy and
emotionally dependant. You must realise that your relationship must
evolve and mould her better and being better is
BASED on her own personality and
NOT your preception of what it should be.

Different race relationship has their own unique
form of problem. Once passed the parent's stage - next come the
competitors.
You can't stop people from liking or chasing your girl - you are
only defend your relationship with power of love. Embrace this
theory and you will secure high trust in your relationship.
What's with competitors? Humans, especially guys, are like that.
Once relationship doesn't fall under the traditional version
(Racial relationship, Long Distance relationship, Older woman,
younger guy relationship, etc) - they sees it as a weakness that
could slip in easily - failed to realise that this weakness could
be strength of the couple because if both party wants it to work
out - twice the effort is being put in as the relationship is being
faced with constant threat.
Love grows stronger with emotional strength and
challenge.
Grow irritated and everything else is natural. Your gf has nothing
to hide, nothing to keep - she is the kind of woman who is open and
live to her emotional conscience. From here, you can see that she
is able to secure the kind of trust and stability because she
BELIEVE in the relationship.
See how confidence she is when she told you that even though she
would bleed when you leave (if that was your choice), she would let
you go? 
External factor will try to ruin and destroy you - but how will you
shield yourself? So what if the guy msg your gf and say if he has a
chance and all the crap? Why get angry over how hypocrite you think
he is when he cannot make it? You can't stop external factor - you
can only believe in your love and work to make it
invulnerable.
This relationship is of medium to high intensity. Your next lesson
would be to evolve yourself. Learn to see correct positive value in
you because she has saw the good out from you apart from the lamer
engineers, etc. Treasure yourself and always fight a self esteem
battle to surpress all negative look-down-on-yourself
thoughts.
If you have fallen, who will fight for the relationship?
Cheers
