You cannot be sure until you try. Both men and women have a big responsibility for the deal. Like an accepting to be scammed – no one will force you to give your personal information in case you do not trust your person. If you do – there are lot of others to blame, right? UaDreams follows their own antiscam policy – they do not allow to exchange private contact information till the moment of the first meeting. But taking into consideration all the seriousness of communication with any girl it is hardly to say what to do. But my advise: first come and see, check by your own eyes – you will never know if this lady even match you. For example you have been communicating with her on any free website for months or years, then you crossed to personal correspondence and it seemed nothing can ruin your perfect future...until you meet..and understand that you do not like each other at all! I consider such trip like UaDreams offers – one of the best opportunity to enjoy your time without any responsibility at least. You get what you pay.
