a question of timing

So... when do you tell your kid that you've started dating? I mean, he is 5. It wouldn't be so much hey, I'm dating now as it would be here, meet the guy I'm serious about. But at that, when has enough time passed? Johnny is still wrapping his head around the idea that mommy and daddy aren't married anymore. Obviously we're nowhere near that point quite yet because he wouldn't handle it well at all, but it still poses an interesting question. And really, for any of you who know me, I don't fall that easily but when I do, I fall hard and fast. While I've only really been in love twice, I also have grown and experienced enough to know exactly what I want and need in a man. When I am certain that I have who and what I want, it is going to be hard for me to wait around. As within all aspects of life, I am struggling to understand balance. Where is the line drawn that takes Johnny from unready to handle something like that to good-to-go? He is 16 years younger than I was when my parents got divorced... I don't know how to approach it from that age/angle. I know that it took me a very long time to adjust to the idea of my mom remarrying, (she had been married to my step-dad Chris for about a year before I was finally okay with it) but Johnny hasn't experienced much of life yet... how much does he really comprehend time in longer amounts than days or weeks? How long would it take for him to stop seeing mommy and daddy as a single unit and instead view us as two different parts of his life? Moving into a new house away from the one we once shared together as a family will be immensely helpful, I'm sure. But still... I have no idea how (or when) I'm going to do this.

Little Man doesn't handle change well. I wish my adult life and choices didn't impact him so much.
