Hi /r/elationships!

I have a girlfriend that I love very much and I see myself on the long term with her but I have the major problem that we can't seem to talk about difficult things in life ( examples will follow).

We come from a relationship where we rushed a lot of things and did a lot of arguing. We still argue quite often and communication can be difficult at times.

Whenever I try to bring up a topic that is difficult for her to hear she flips out and think I'm aggressive and mean. For example lately I believe she has changed a lot: she has become a lot more cynical about things in general, particularly her (very good) job and her chances of going full time. From what she tells me her motivation and performance are down which indeed hurts her chances to move to full time.
I tried to talk about this subject and her general well being but she became very angry  and told me that I'm not her parents and to leave her alone. I tried to explain that despite not being her dad I still care about her very much and since we share a life together her happiness and well being is very important to me. 

I personally believe that she is going through a phase where she is suffering but I might be reading too much into it. When we first began dating I helped her through a lot by finding her a good job and provided for her so I think that my opinion and advice are not completely bad.

What's your opinion on the matter? How can I bring up these subjects? How to tell if a woman is suffering?
Should I just stay on the side and see her go on a dark path? What's your experience with experiences like that?

Thank you for your comments
