Don’t talk about your future, because you will lower your chances of being in it. Let her be the one to bring it up. You need to make it her idea. It’s like that in nature. You see a lot of animals competing for a female, and she decides which male she’s actually going to mate with, who is suitable, and who is acceptable to her. It’s the same thing with men and women. Women are going to decide who they want to date exclusively, and who they don’t.
