Hi,
butt joints can be a pain in the butt. Sorry for that. Couldn't resist :-)
One of the problems with butt joints is that end grain sucks the glue away from the joint, like paint on end grain.
That is probably why your joints failed. They ended up too dry and so little or no bond. You have to apply glue on the joint until the wood sucks up no more up, then some more so that there is enough glue for the bond.
Hope this helps.
