Sorry, I am seeing someone right now. That is the response that I recently received from a new web match. So, yesterday she was available but today she is not? I don’t think so. I suspect that she has been hedging her relationship. That is, she is dating someone but looking for something better.
But, more to the point, most of these dating site have a provision to shut down matches temporarily should you find Mr/Ms right. If they are keeping their site open even though they are seeing someone then they are just playing games. Maybe that is why they are divorced in the first place.
