At this time, you did not know the importance of personality which is another element when it comes to attraction. The way the person acts around you will give off a certain vibe or feel, making you a happier person when around them. If you feel nervous and not so sure of yourself, it's a good sign you have not known them for that long. Not to worry, there are a few things you can do to change this.
The third law of attraction has to do with desire. Why do you want to be with this person in the first place? Do they make you feel special or are you just trying to get ahead in life with your personal image? By dating someone who is much older than you are, what you are doing is showing people you are ready for a commitment and are serious in your relationships.
