  Employing a recently developed many-body technique that allows for the
incorporation of thermal effects, the rich phase diagram of a two dimensional
two orbital (degenerate $d_{xz}$ and $d_{yz}$) Hubbard model is presented
varying temperature and the repulsion $U$. Our main result is the finding at
intermediate $U$ of a novel antiferromagnetic orbital selective state where an
effective dimensional reduction renders one direction insulating and the other
metallic. Possible realizations of this state are discussed. In addition we
also study nematicity above the N\'eel temperature. After a careful finite-size
scaling analysis the nematicity temperature window appears to survive in the
bulk limit although it is very narrow.
