Is it normal to be jealous of your boyfriend's ex?
Yes, it’s normal to feel some jealousy about your boyfriend’s ex, especially if you’re comparing yourself or feeling unsure about where you stand. It’s worth paying attention to whether the feeling is occasional or starting to drive arguments and monitoring.
A little jealousy about an ex is common. The ex can feel like a comparison you didn’t ask for, even if your boyfriend has given you no reason to doubt him. Feeling jealous doesn’t make you a bad partner; it’s what you do with the feeling that matters.
If it comes up now and then, talking calmly about what would help you feel secure can be useful. If you’re repeatedly checking up on the ex, interrogating your boyfriend, or getting stuck in comparisons, it may help to look at what’s fueling the insecurity rather than treating the ex as the problem.
