Was He lonely? Was He bored? Neither of those will work, because they would contradict the "perfect nature" of God. A "perfect being"....wouldn't get lonely. Loneliness would indicate a longing or a painful absence. To create a being like Man because "He wanted to show his love" would also indicate that He NEEDED to be loved in return and again show loneliness. If He was bored, it's worse....because a "perfect being" shouldn't suffer from boredom since they would either be incapable of such a need for distraction...or have infinite capacity to distract themselves without creating an imperfect Cosmos and an imperfect Man.
