The real deal is that the arising of insecurity is an involuntary issue and only a few people may fully understand and stay aware of their own insecurities which might be interpolated in a new relationship and other relationships as well.
It’s a fact that most of the insecurities brought into a new relationship were acquired from past relationships. Too much insecurity will make you face those horrible, self-destructive, abusive relationships.
It’s important that insecurities be addressed and handled accordingly or else it may grow into something really terrible. Communication is very important for a healthy relationship. Don’t just assume, always have the time to question, ask and move on.
Insecurity will make or break a relationship, and from what I have seen, people with security issues are the worst offenders. They have had to fight for themselves all their lives, finding themselves in endless abusive relationships, with the damage occurring again and again. They can’t trust anyone, so they feel they must be in control and must treat the one they supposedly love like a dog.
Insecurity makes you think poorly of yourself and if this happens, you might begin to wonder what your partner sees in you. You will start to question why she would want to stay with you and it may even start you down an even worse path. You may think that she is looking for someone "better".
Stay away from this by starting to combat this by getting secured with yourself. Understand that you aren’t perfect, but your partner is with you for a reason. He/She may see things in you that you do not. It is important that you have good self-esteem if you want to fight insecurity in your relationship. Remember that insecurity can cause detachment and can make you act stupid even if your partner has done nothing wrong.
Relationships are about compromise and trust. If insecurity is brought to a relationship from the start, you are never giving that person a chance to prove to you they are not the same as the last. Thus the insecurity continues and strengthens. We are the only people who let our insecurities cause us to make up facts in our head and act on them as if they were proved.
We must walk into a relationship with an open mind and learn that we are sharing our life with a person who loves us and will prove us despite our differences, our relationship will work.
