Coelogyne mayeriana growth issues

[SundayGardener]

I purchased a Coelogyne mayeriana last September. This was an impulse buy, made at my first orchid festival in Chicago just as I was approaching the point of checkout and the endorphins were high. I hadn't done any research on it.

So now I have, and realize it was not a good buy for my conditions and abilities, but that aside, its growth is becoming problematic. It has this side "branch" that is quite heavy. Right now, I have some wires (I make sure they don't cut into the orchid) holding it up in its normal location.

When I look at pictures of other Coelogyne's online, they all seem to be happily contained in their pot and not trying to turn into a tree, but typically internet pictures don't capture the full story! Is this, as I suspect, the main rhizome extending off to the side? Should I be dividing it, or propping it up? I can't capture all that in a single pot!

Thanks!
