Well, I'm definitely less happy when single, though not to such an extent
Its that transition period between not-single and single, or almost-not-single and aww-crap-I'm-single-again that I hate the most.. such an emotional rollercoaster.
I'm much more cautious now, so I see my current single-ness as a time to analyize my past mistakes, re-calibrate my instruments, and find a truly compatible subject
There is much hope here! So many opportunities.
