I think the images are here. I think the idea is here. I think you're on the right track. BUT, i also think this lacks voice. Let's go back a bit to the first best bit of poetic advice a poet can get: Show, don't tell.
Now, there is more to it than that, but in this particular piece, I think if you keep those words in your head, you'll see where you can clip, strip, and reconfigure this into something a bit more asthetically pleasing.
Some people, sometimes, need space
let's start at the beginning: "Some people," -- in this case, why not illustrate? The abstract 'some people' is far less intriguing than say, 'oopity doopity people' or 'mop haired freaks, so-fine chiqs and the fribbulous dips between' ... whatever.. the point is, 'some people' doesn't own the reader. YOU are the fuehrer here... you are the absolute dictator of your audience. Tell them what they feel, what they want, what they see. 'some people' doesn't do that. Neither does 'sometimes' ... and even space can be expanced, or painted to tell them exactly what you want them to believe.Close as you may be, long time friends
Closer than family, and then
A split, a rift in space time
A gap that seems insurmountable,
But is a loop, a closed möbius strip
You can find you way back
Trick is to head in the right direction
Left works just as well
Because friends can always come together
Again at any time

I was sent the most amazing piece of writing advice the other day, write it, then totally rewrite it. How fun, huh?
I like the content, but I too am playing with the flow of it. I'm starting with simply:
Space.
Now, having said that, I LOVE imagery, and agree with Stephan as far as "show me". I also love an artists wish and right to be true to their own style, so, you go with what fits on your shoulders, or, lol, with what you want to shrug off those shoulders.
The other greatest piece of advice I've gotten? True art is achieved by breaking though to what makes us uncomfortable. Cool, huh?

I don't have as much technical advice to offer as Anstey, but I can tell you that I love the core of this. As a person who seems to need much more space than my beloveds (friends and family alike), I appreciate the acknowledgement that space is, in fact, a part of healthy relationships!
Love the ending. The older I get, the more I find that dear friends with whom I've lost touch tend to pop up again as if no time has passed. It's a beautiful thing.
Go back and tell me more, give me more details (in showing, not telling). Yes, revisit the idea of the mobius strip and see how you can get more mileage out of it.
