I got your concerns. This is my advice:
1. You are concern about whether she loves you or not. It's because
she is too good to love you this much is it?
The solution: Don't worry about it! the more you worry, the more you will reject her love. Just accept her love and appreciate it! That's all you just need to do.
2. You are concern about the
relationship is going too fast. Maybe in your past relationship haven't been that fast and you feel insecure.
There are people who know each other for months and married. They had a great life. It is just out of your imaginations, not impossible and anything to worry about.
3. You afraid that she will leave you?
The solution: Don't worry this. Remember this! The more you worry, the easier you will lose the relationship. It's because when you worry, your body and your face is all written worry. People don't like to be with worrying people and will resist automatically!
Don't worry anything. Relax and enjoy the relationship. Just create and commit to her that you always want to be with her whatever happens. If you still worry, I have nothing to say anymore!
So, cheers
My worries lose my previous relationship before. I don't want you and others to be a victim too.
