When you meet someone in person, you instantly have a first impression about them. A lot of this first impression is based upon body language, chemistry between the two of you, and eye contact. Obviously, this type of impression is impossible if you are meeting someone for the first time online from dating sites. However, even though it may be harder to determine what a person is really like from an online interaction, you can still learn to trust your instincts.
Dating should be less about matching outward circumstances than meeting your inner necessity.
