Scotty: I particularly like Darren's advice about joining a club or society and just naturally see where it goes (in fact, this is something that I will also considering doing). Also, as another thought for you to ponder, I am wondering if there is any possibility that you are moving too quickly to meet someone else? Have you finished your "grieving" period? If yes, that's great. If no-perhaps you are trying to meet someone to quickly instead of dealing with your feelings first.--And if I am way off base with this thought, I do apologize.
Also, perhaps you could be trying too hard or coming off that way. Others tend to sense these things. I guess I'm saying that I think Darren's advice is excellent. Just slow things down a bit and when it's meant to be it will happen.
