Jealousy can be a strange and powerful feeling. It’s closely linked to self-esteem  and may reflect how confident you feel in your relationship . The more confident you are that your partner is committed to you, the less you’ll worry about them leaving you. If you’re not secure in the relationship, then it may not take much to set off your jealous feelings.
Jealousy itself won’t necessarily do your relationship any harm , but acting on jealous feelings can be very destructive . Left unchecked, jealously can lead to behaviour that you might not be proud of – seeking constant reassurance, making accusations, becoming possessive, and even threatening to break up .
The following tips can help you boost your self-esteem, increase your confidence, and start to deal with your jealousy.
The next time you feel jealous, remember that it’s just a feeling and you don’t have to act on it. This might not be easy – if your usual responses have become ingrained over the years, it might take you a few goes to change things.
Breathe slowly, and notice the thoughts and feelings you are experiencing. You may feel angry or anxious – that’s OK. Just accept that it’s happening and give yourself a chance to reflect before you act.
When difficult feelings come up, it’s usually easier to deal with them straight away . Talk to your partner and try to focus on describing your own feelings, rather than their behaviour. Let go of blame, and explain to your partner that you sometimes get upset or worried about losing them. Be clear that you’re not asking them to change anything, but that you’re trying to deal with some unpleasant feelings.
Give your partner a chance to respond. You may find it helpful to ask what would be the best way for you to talk about similar feelings in the future, so you can build up your own way of communicating about your feelings as a couple.
Like other forms of worry, jealousy can lead you to focus on the negative, and misinterpret your partner’s behaviour. Remember that your jealous thoughts don’t necessarily reflect reality – you may think your partner is interested in someone else, but that doesn’t make it true.
Take some time to reflect on the deeper feelings behind your jealousy. If you are truly afraid of losing your partner, ask yourself why your confidence has been rocked, and what you can do about it.
Sometimes when we have low self-esteem, we can read meaning into things that have nothing to do with us. If we’re feeling down, we might see someone yawn and assume it’s because they find us boring when, really, they might just be tired.
The same can happen in your relationship. When something happens that makes you feel jealous, ask yourself what else might be going on. Sometimes people dress up to feel more confident amongst their peers, and not to attract a new partner!
You can improve your confidence in the relationship by working on your communication skills with your partner. Make a habit of praising each other, planning fun experiences together, and being on the lookout for positive behaviour from each other. Over time, this can help boost your self-esteem and strengthen your relationship.
You can never know for sure that your partner won’t leave you. It’s instinctive to want to protect yourself from the fear of rejection, but uncertainty is a part of life and a part of every relationship. When you accept this, it can give you a new sense of freedom to stop worrying about what your relationship might become, and get back to enjoying what it is.
