How can I stop being insecure in my relationship?

Tell them how you feel or be with someone who is considerate of your feelings/ someone that makes you feel comfortable in your own skin

Once you realise that if the person your with wants to be with you then they will stay, if they don't they are worth you being insecure.

You can stop being insecure about your relationship understanding that the other person is with you because he/she chose to be like that. Not because there isn't other alternative. Nowadays people break up qhen they want. If it's not your case, then no need to worry.

Feeling insecurity in a relationship can be quite troublesome. My own personal experiences have taught me that it's good to discuss these insecurities with your partner and / or friends. Discussing these problems with the people you know best can give you perspective. If that doesn't give you the answer you think is right, I'd recommend you to seek out a therapist.

My trusting your partner and giving them the freedom to be what they are. When you are not insecure, he/she will start to express more.

take a long time to choose my partner before going in any relation and know the personality more and more

No relationship can succeed with out 2 people working together and having open communication if your struggling or feeling insecure you need to convey that to your partner

Believe that you are lovable and that you are worthy of positive regard. Feelings of insecurity might crop up, and while they do, try to remember that you are deserving of love and positive regard.

I would suggest allowing yourself to be open to trusting someone, it's definitely hard but telling yourself that this is an important aspect in a relationship really helps. Try to ask your partner for reassurance when needed be if he/she is ofcourse okay with that. Maybe that would help you feel like you are trsuting him/her and will push through the doubts. Also, maybe you should look back to why there is mistrust in the realtionship and try to find solutions that work for you don't be scared to try new things and see what helps you best. :)

You need to build a good foundation. I understand that we all are results of compound situations in our childhood which is usually the root of lack of the trust and feeling security while being in a intimate relationship or any other relationship in our lives. This is my personal opinion, I started working on myself because i hardly trusted anyone and was highly insecure about myself without even realising. It made me toxic unintentionally and would lead to unnecessary fights or argument and thus the pain. I sat and thought things out, it took me months to work on. Firstly I started journaling my feelings. write it down. Regardless how it sounds or if it's rational or not. Then i started applying some techniques of CBT. that is breaking down and dissecting my thinking pattern. I would ask myself, what happened? How does that make feel? Then... Is that what actually happened? Or did I perceive something due to my truama filter? Was my reaction rational? What possibly could trigger me? With my relationship, i started involving my partner. I would take a break when enraged then come back with cool mind and tell him how i felt and why. He responded better. Slowly we build repor and our foundation got stronger with time. Next, self worth is super important when it comes to insecurity. When you are in a relationship, you should be sure to have a life of your own. Your life shouldn't resolve around the relationship. Thays a part of your life, not your life. Keep your hobbies and engage with friends. Alot of people fail to do so which results in clingyness which is usually the result of insecurity and fear of abandonment and loneliness.
