Online dating help???

I met this guy online about 4 weeks ago. I asked him if he wanted to meet and he said he wanted to chat a bit longer. Its now 4 weeks and I am too scared to ask him again to meet. What should I do? Should I ask him, and what should I say? I really like this guy but I am not sure whether or not to pursue him or just move on and 'disappear'. PLEASE HELP!!!

My advice is...give it a deadline....say for example - 2-4 weeks of chatting and if he doesn't mention it then i'd either ask him if he is ready to take the next step to meet , or move on hun. he might be a little scared or wary.
