Impossible to know for sure. Long lasting relationships take years to fully develop because you need a lot of time to really know each other, the good, the bad, the angry, etc. So just relax and let things develop over time. Sounds like she is latching on to you and planning your future and you don't want that yet.
You should be honest with her when she starts her lifetime planning and tell her....."I just don't know" as you say above.
Ok, so she is still with you and you too are planning for the future. Well she is planning for the future and you aren't sure. If your not sure then who is?
Also being not sure is like sitting behind the wheel but not holding the wheel and drifting down the hill. You are going to be heading for a crash. If you want it too last then take the steps to make it last.
Be a participant in your life. If you love her then let her know, if you also want to share a future with her let her know be get engaged. Also, being in college don't allow yourself to run around with other women.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
