If your other half is acting more angrily and started fights for no reason this could be a sign of cheating, especially if your partner is a man.
Private Investigator and managing director of Lipstick Investigations David King said: “If men are guilty this can manifest itself as anger. Husbands will often manifest anger into a relationship, and this can sometimes work as a way to get out of the house.”
