If I fall in love with a girl with the same personality and constellation as me, will I get anything? First date, comment?

We can't help you. This kind of thing has to be solved by ourselves. Give yourself some time to think clearly first, and don't jump to conclusions. Think about her character first. You should know what kind of person she belongs to, and try to make her change of heart with your sincere actions. If you can't, then try to put down your dignity and get down on your knees to propose to her. It's not that you can't, but that you haven't done anything yet. I believe you can. Come on!
