[Revenant]

We got aquainted at the universuty. In some time I started to feel something unknown when I saw her. In some more time I told her about my feelengs. I couldn't take it any more. She was very pleased to hear that. I was so happy when we started dating, but then...
I recognised I've never seen so much philosophy in one teenager. She is so hard to understand... Besides,despite my feelings, she doesn't belive in love at all!
There is so much unknown in our relationships...
Crazyness...But I still love her.

How would you call this kind of situation?
And what would you do on my place?
