How do I deal with jealousy in a relationship?

First work out what is behind it: a past hurt, insecurity or a real change in behaviour. Tell your partner what you feel without accusing them, and ask for reassurance, not control. Checking phones and tracking locations usually makes things worse. If jealousy is severe, a counsellor can help.

Name the exact trigger, such as late replies or a certain friend, and share it as a feeling, not an accusation. Ask for one clear thing that would help, like a heads-up when plans change. Work on your own confidence too, because jealousy often points to a fear of not being enough.

Yes, the early rush fades and desire changes. Keep attraction alive with new experiences, affection outside the bedroom, time apart and honest talk about intimacy. If you feel distance, tell your partner kindly. A counsellor or doctor can help if there are deeper issues.
