Online relationship is very popular today and many people meet potential dates this way. In order for the relationship to develop into something real, sooner or later, you must meet your online date in person.
A lot of people are leery about meeting someone from an online dating site. There is a risk involved if you don't use common sense and keep yourself safe. There is also the chance the person you have fallen for has misrepresented himself or been outright dishonest.
The only thing you can do is give it a shot and see what happens. Just like meeting someone at a club, there are many failures before you connect with the right one. Don't expect the first offline meeting to be perfect. Your date is probably nervous about meeting you too so you should work to put her at ease and make her feel excited to meet you in person.
Your first meeting should be cautious and safe. In case your date is a wacko or predator, you need to be able to get away safely. Plan your date in a public place and meet there. Do not get in a car with someone you don't know. Have your first date in the daytime in broad daylight around plenty of other people. Do not drink alcohol or be impaired in any other way. If you or your date wants extra security you can arrange a group date where each of you brings along a couple of friends.
Activities for a first date vary among couples but you probably want to go somewhere you can get to know each other. If you go to the movies you won't be able to talk very much. If you go out clubbing it may be too loud to have intimate conversations. Choose a quiet place instead like a coffee house or a restaurant. Do something that both of you're interested like playing a game of golf or badminton. If you are both physically active, then you could meet at a rock climbing place. Try to pick something you both enjoy.
The goal is for each person to feel comfortable on a first date. If one or both of you are having a bad time, then it is acceptable to end the date early and part gracefully. If you have a great time on your first date, then you're glad that you took the plunge and met in person. You'll be ready for a second date. Just remember, it is hard to predict what will happen with your online relationship.
