The situation could be as simple as not liking their personality, or wanting something else. Think of something that could have really got in the way — something that usually makes you cancel your plans. They've already postponed the date at least once. If you act life a freak like I used to you are simply gonna kill the attraction between you two, and you will, consequently, lose value to her eyes. Let the other person down smoothly, and don't ever lead them on. That can emerge deeper into relationships. The thing about serious relationships is that when we're in them, we expect to be taken seriously.
She canceled the date… what to do now?
If your date has postponed your date oncetwice, or even three times, there's a good chance they will "postpone" again. There are no comments. They've already postponed the date at least once. That golden rule you learned in kindergarten actually applies in the real world of relationships: Treat others how you would want to be treated.
