How to keep these leafs upright?

Recently I aquired this plant, and my issue is, when the leafs grow a little bit bigger, they completely bend down and lie on the groud and eventually die. What should be the lifespan of theese leafs?

Is there any way to keep them upright and stop them from dyeing?
