Yes, it may be a bit too soon after a year and few months to make a big move. All depends on yours and her goals for the relationship and your comfort level.
She may have been influenced by her parents and told to go ahead with this change. If you know her parents, you may want to have a dinner with them and your girlfriend and kind of discretely bring this issue up.
Some things to focus on would be your short term goals and those of your girlfriend. You may want to have a discussion with her as to where she sees the relationship going in the next 2 years, 5 years and where the two of you see yourself professionally and otherwise in life. If there are discrepancies, you would want to work on those issues (couple's counseling, self help, etc)
There should be no confusion as to "what to think"
She is trying both options and is doing what works for her. Both of you are too young to move it (especially when this sort of things are happening)
Actions speak louder than words. You will have to take care of yourself as well. No one likes mind games.
I would be available to answer further questions upon acceptance of prior feedback since its generally one question and answer site. Thank you.
