Some people are more prone to jealousy than others, but virtually everyone is more jealous in an unstable or unloving relationship. After all, jealousy is centered on the fear of losing someone. If you’re unsure of your spouse’s love or your child is unclear whether you love him or her as much as a new sibling, jealousy is much more likely to become explosive. Indeed, in relationships that are already troubled, jealousy may be the final nail. Because jealousy is heavily influenced by the quality of a relationship, practicing loving communication and taking time out for one another is an excellent way to protect against severe jealousy.
The unique dynamics of a relationship can also affect jealous feelings. When there’s a mismatch in relationship styles, it can be a recipe for jealousy. Attachment plays a significant role in jealousy, and people with insecure attachment styles can be more jealous than people who are securely attached. For example, a husband who needs a lot of attention and reassurance might be more prone to jealousy if his wife tends to like her personal space. A highly social husband might make his more introverted wife jealous, particularly if she’s not used to having the large number of close relationships he has.
