happy with who I am and where I'm at

I am single and have been for a couple of years now.
Okay more than a couple.
I'm actually very happy with my relationship status.
I have never really felt defined by being in a relationship like some people do.
I finally found a woman that I trusted enough to have kids with but it was late in life. And when we divorced I didn't feel the need to replace her.
So overall the relationship did what it was supposed to do.
Now I have three wonderful children that are my world and that is all I am worried about as far as any relationships go.
