Like people visit match makers before arranged marriages with a list of preferences about their spouses. On similar lines, online websites are like matchmakers with various profiles, providing many options to choose your soul mate. Family is very important factor which unites people in marriages. Online dating websites ask for family details so that it's easier for people to match family attributes before they start dating.
Even if you are using online dating websites for establishing serious relationships, do not become a serial dater. Everyone goes through ups and downs in life. Do not let the bad times overpower you and make you addicted to dating. The best part of any dating is the mystery and thrill attached to it. If physical relationship is built very early, emotions might not get a chance to catch up and thus the relationship might be based on a weak foundation. Such relationships are likely to end soon. Therefore always establish an emotional bond with the person and then look forward to enter a new phase of life with that person.
