No one is insured against jealousy and it’s important how you build your relationship from the very beginning and how your loved one feels. This is an interesting statement and applies to people who have common sense and are sufficiently confident in themselves. But most people are so complexed and insecure about themselves that no matter their partners do, they will never feel secure if they consider them in some way more attractive or more successful than themselves For me jealousy is not a logical response to a certain behavior. In my opinion, a jealous person is, for example, one who starts thinking about betrayal if his partner doesn’t answer the phone after the third ring.
