I was never into online dating - tried it before and it didnt work - but for the lack of opprtunities to meet guys I decided to give it another go. I met a nice guy on a dating website, we used to exchange messages every day and then when I was going to London, decided to meet up. I really liked the guy, he seemed to like me and the meeting was going well...afterward we exchanged some texts along the lines that it was a pleasure to meet up and he suggested that next time he would visit me. Even the following day he e-mailed me something similar and all seemed to be going well. But from the next day onwards - nothing! It has been 5 days of no contact whatsoever from him - he even hasnt been online and I guess he hasnt read my last message to him. I sent him a text to ask if he was ok and the text was delivered but no reply. I guess this means he is not interested - fair enough - but why all the hassle? Why all the "pleasure to meet you" and "I will visit you next time" nonsense, why keeping in touch for the first 2 days and then pretending he doesnt exist anymore? I mean, surely he could still come on the website (just not replying to me) to talk to other girls, surely pretending he disappeared is a bit unnecessary? Oh well..... 
Sadly enough something similar happened to me in real dating too - recently I met a guy on a night out who seemed nice and we had a good time, when saying goodbye, he asked for my contact details - only to never contact me again!
I mean, arent men supposed to be simple and much more straight forward? Why all the rubbish talk when it would be so much easier to say bye and leave it at that?
