Is it normal to be jealous of your partner's past relationships?
Mostly.Normal for most people
Yes, it’s normal to feel some jealousy about your partner’s past relationships. It matters more how you handle the feeling than whether it shows up.
A little jealousy can come from comparing yourself with an ex, worrying you won’t measure up, or wishing you’d been part of your partner’s life sooner. Lots of people feel it, even when they know the past is over.
You don’t have to love hearing every detail, and it’s okay to ask for reassurance. But repeatedly questioning your partner, demanding they erase their past, or letting jealousy run the relationship can make things painful for both of you. Try to focus on what you and your partner have now, and talk about what would help you feel secure without turning their history into a trial.
