Paranoid:

Paranoid personality disorder is characterized by a distrust of others and a constant suspicion that people around you have sinister motives.

They search for hidden meanings in everything and read hostile intentions into the actions of others. They are quick to challenge the loyalties of friends and loved ones and often appear cold and distant. They usually shift blame to other people and tend to carry long grudges.
