How can I stop being insecure in my relationship?

Be completely honest! When being honest, there aren't any secrets between you, allowing you to feel closer together.

communication is really important! let your partner know how you're feeling and you both and support eachother :)

First of all, ask yourself what makes you feel insecure. A relationship is built on 4 important things: Trust, Communication, Understanding and Honesty. If these are missing then the relationship is bound to crumble. Furthermore, sometimes we tend to be insecure due to our own personal experiences e.g. past relationships. Take time and figure out what you want from your relationship and communicate those feelings and thoughts with your partner.

You can talk to your partner about your insecurities and have them reassure you. You can make a list of the ways your partner shows they care when your insecurity is starting to take over.

Be yourself. Stop letting the other one put you down, speak up for yourself. What you think should matter more than what the other one thinks.

Be open with your significant other. Open up to them like you wouldn't to anyone else. Enjoy every second with them and ask them to do the same with you.

Sometimes the best way to overcome insecurity is to start by focusing on the areas of yourself you DO like. Once you're able to appreciate the great parts of you, it can be easier to forgive yourself for your faults or weaknesses. And always remember: no one's perfect, and we're all works in progress. Always allow yourself to be human.

Insecurity is often about seeing problems that don't exist in relationships, then feeding them, allowing them to take hold and create monsters. Focusing on the good that is there is a good way to combat insecurity. Often times it only seems like the problems that create insecurity are destructive because the good things are overlooked.

You can stop being insecure by learning to believe in your strengths to build confidence as you acknowledge what is difficult you can learn to let go of things out of your control.

Firstly, if you are insecure you should never start investigating your partner in a creepy way. Because that will only cause you more pain and will drive you crazy ending up in senseless ideas. The best thing you could do is talk to your lover about it, talk to them about what you are feeling lately and ask them to be honest with you. If they lie to you, it's their problem. Not yours, because you have done what you had to.
