TruthApple came from a good angle also, here's my 2 cents.
In the end she is just a stranger that is kindly declining your request for any relations concerning herself and you. And she can, so can you if someone would approach you and you could not be bothered with their presence at that time.
Too bad for her she is missing out on a great opportunity to meet such an awesome guy such as yourself, her loss.
Rejection is a strong word, what I have learned from Vince Kelvin is; She has NO AUTHORITY to reject you.
You might think this is contradicting to what I said first, however, the difference lies in whether you really want to go for it or not.
If she tells you; ''I have a boyfriend.''
Would you let that stop you? Are you going to take it as a rejection?
There are so many women out there, really. Ever been to Vegas? NYC? LA? I see you're from Germany, so maybe Amsterdam would be a better example even...
Go to just these 3 or 4 city's and approach like crazy and I am sure in just the first city you would visit you would get good results.
Go for it...
