I think you should get the camera. What camera is it, btw?
What will you be photographing? Will you want to take pictures of children/people? Buildings? Nature? Everything??
Also, how much do you know about photography? A lot? Little? If a little, are you willing/wanting to learn more?
I see definite potential in those pics. You really DO seem to have a knack for taking pictures beyond "snapshot" quality. Though, they would technically define snapshots, they go creatively beyond that, I think. You get in there and take pics in the moment, you angle your camera to get perspectives that aren't always seen, of if they're seen, they're forgotten. And that is why I think you definitely have potential.
You could always try the whole "get-your-husband-involved-in-your-hobby" route, like I did. I asked his opinion, and for his help with certain photographs. I told him of a photo project I am wanting to do, and now the wheels in his head are turning and he told me last night where he wants to take me for my next fun "shoot".
And you say that you don't want to make a career out of it (and neither do I), but you never know how good you'll get and you might find yourself stumbling upon some freelance work unintentionally.
