DARK SIDE????

this scares me.
several years ago during an anniversary dinner, Don and I were talking about how well we knew each other and I maintained that he really doesn't know me very well, he is not that involved in my life or our relationship to know my every move or thought.
I could get away with murder, lead a double life....Don't worry, I don't.

a little over a year ago we had a similar discussion but with the emphasis on I have no way of ever knowing how he feels about things, what he thinks, what angers him or fuels his passions.

The scary part:
Both times he has eluded that he has a "DARK SIDE".....

WHAT THE H E DOUBLE TOOTHPICKS DOES THAT MEAN????

Is he depressed and does he think of suicide? Is he violent and could hurt me or somebody else? (his actions say quite the contrary that he would never fight for me or on my behalf). Is he having thoughts about another partner? Does he not believe in God really? Does he already have a double life?

Last night we went to a counselor, our first appt. He said he has these dark thoughts and he sometimes is depressed, but he didn't say what these dark thoughts are still.
