Re: What would you not tell your wife, or girlfriend.
Here's my take on this and I've been married for twenty years.
Yes, there are things I don't tell my wife. Here is why. I still have a life, I have the life I had when she met me and the life I had when we got married and that life didn't go anywhere after I got married.
Now, that life is mine, it is nobody else's. And I see no reason to be convinced that my wife would prefer that I stop living that life, even though there are parts of that life that have nothing to do with her.
I can tell you right now that my wife doesn't tell me everything she does for one simple reason: it's none of my business. I don't want my wife to become any of the sterotyped things a wife/companion is supposed to be. When I met her she was a very interesting individual and I like her just that way to this very day.
She's her own person and I am my own person. And we sure do have a hell of a lot of fun when we hang out, just the two of us.
