If you are looking for a potential partner or a long term commitment in a date, it is better to be sure. Make it worth of all the effort and time you put in for that relation. Here are some points to keep in mind when you browse profiles for a prospective match.
Pay attention to their hobbies, interests, occupation and relationship status. These are simple things anyone can be truthful about. If they have shared something with you on the phone or through mail which actually is different from what is published on their profile, you must understand that they are not honest, plain and simple.
Usually either men or women immediately after a failed relationship sign up for a dating site. Just out of sheer boredom, depression or plain loneliness. Their profile may be impressive and they may be a good match for you. It is important to find out if they are ready to get involved in another long term relation.
Another type of people to be wary of are those who can easily fall in love, without even getting to meet you in person. However much you may chat, exchange phone calls or use the web camera it is still not sufficient. You both have to physically meet in person, for real. Anyone declaring their love to you even before meeting you is just not right for you.
There are people who want to be friends first and then see how it goes. I seriously think that such people are actually unworthy of a long term relation. If they want friends then why look in a dating site? When they cross the friendship territory but are still unable to commit, all they have to say is “hey, I already told you, I just wanted to be friends”. So, never even consider them as a prospective match.
