5 Your partner is jealous
People who have already been unfaithful know how easy it is to take action and therefore believe that everyone is unfaithful. If you start dating someone who spies on your every move from the start, you say something like, “I’m sure you left before going to see another”, or criticize the way you dress or your behavior with others; run away as soon as possible!
6 he’s selfish
If you always have to do everything your way, if they never accept an opinion that differs from their own, if they find it difficult to share or if they demean you all the time, then they behave like a person unfaithful. Selfish people have this ability to rationalize and justify infidelity with much more ease.
