I've tried a lot of ways but it's not like that
Tell me how to do it better or more correctly?
How to surprise a girl?
You probably just lose your time with her. If you have tried a lot of ways then she may clearly see you want her, if she rejectes you then she does not need/respect you.
If good relationships between people is possible then it should be clearly seen for everyone, it is not so complicated. Surprise and love only girl who appreciates you
