My girlfriend broke up with me saying she can't see herself marrying me?

I feel like we had a good relationship, we got along had the same values, kissed a lot and I did everything I could to be good to her. She broke into tears and told me she just can't see herself marrying me and that it doesn't feel right.

What does this mean?

Should I move on or just give her some space for a while?
