Continually working late
Perhaps this is one of the oldest excuses. You will know that something is wrong, if your partner starts working late and spending significantly more time at work without any notable increase in income.
Some individuals are either too polite or too shy to call up their partner’s boss in order to find out the truth. In a case your partner is not working late, but is in fact cheating, you should call their bluff and find out from their boss.
Less often initiation of closeness
Your partner may be getting pleasure elsewhere, if he/she either reduces or stops initiating lovemaking relations with you. If there is a decrease in the physical relations, then it is a sign of a declining relationship, and additionally it is an indication that your partner is cheating.
