What should I be doing with this plumeria (tree) that continues to outgrow the trunk to support the leaves?

This tree is probably not getting enough light, so it has become spindly. Can you find a way to give it more light, such as placing it near a south-facing window or giving it an extra lamp?
Meanwhile, you can prune it back (cut off the top, leaving just a few leaves) to encourage more bushy growth instead of just one stem. Or, you can cut off the entire top section and root it to re-grow a shorter plant.
