Sometimes, you just have to let other people let them hurt themselves before they can realize what they are doing.
only meet on her turf: places she's familiar with and know all the exits. Day time only, lunch or coffee. No dinner, no drinks on the first date (I would do first 3 dates if I hadn't had extended conversation with them first)
Well that's always the chance you take. If she didn't learn from that experience I don't know what it will take for her to learn. Just tell her you are really concerned after what happened and you don't want anything to happen. Suggest to her that if she insists on using dating websites, that she go with LifeMates.com or a similar site where the company does background checks on the men that join. It's much safer
Some people have a real problem. Hope she doesn't get hurt.
It is a difficult thing these days to meet people, and the internet it becoming more and more the most common way to find someone. Granted it is not the best way, but it is easy and the rest of the world is becoming so distant with every not having time and becoming more strangers to their neighbors. So the reality sets in that the internet is the most likely place to meet people, it is becoming more unavoidable. Regardless, the same can happen if you meet in the real world or on line. That being said? People are dangerous and time need to be taken. Not saying time needs to be taken before meeting in the world, but always someplace safe with lots of public around you, both inside as well as the parking lot areas, like a local shopping mall. Bars are right out of the question until you have met a few times! Just common sense about meeting someone and taking the time to get to know about them before running off.
