SWF???

I'm toying with the idea of a dating site.  I've done it in the past and met someone that I dated for almost 3 years.  I've done it at other times with no response at all so I think it's a hit or miss situation.  I am so content 98% of the time and I know that I'm a really dull person so I don't know if I want to put the effort out or not!  That's a terrible thing to say but it's true!  I feel pretty blessed that I am so content.  But sometimes I wonder if I will regret staying by myself so much.  Would retirement with someone be better than being alone???  Haven't decided yet!
