Is it normal to feel retroactive jealousy?
Yes, it’s normal to feel some jealousy or insecurity about a partner’s past. It’s worth paying attention if the thoughts take over or lead you to interrogate, monitor, or punish your partner.
A partner’s past can stir up comparisons, insecurity, or images you didn’t ask your brain to serve up. Lots of people feel this sometimes; having the feeling doesn’t mean you’re bad at relationships or that your partner has done anything wrong.
What matters is how much it’s taking over and what you do with it. Repeatedly questioning your partner for details, checking up on them, or treating them as if they’re guilty can strain the relationship. Try to focus on what’s happening between you now, and talk about the insecurity without turning it into a cross-examination.
