When you are in a relationship, you are supposed to remain attached to the person you are with. When you attach yourself to other people and hide it from your partner, it creates a lot more problems. It just creates a barrier between your partner and you, and here is how it can ruin your bond:
Keeping it a secret for no proper reason.
You are in a strong emotional bond with a friend and you have kept it a secret. As a result, that friendship has only taken on a wrong route no partner ever keeps a secret about a friend. Once you do it, you indulge yourself in an emotional affair. A secretive affair makes only things worse, breaks you two apart and ruins your bond..
You begin to hide details.
You ruin your bond with an emotional affair by not only cheating on our partner but by also keeping more things from your partner. You lie more and more often. You lie about where you were, who you were with, what you were doing and why you were there which keeps on piling up to the point that your relationship is based on lies. A relationship that is based on lies proves that you are not a dignified person and that your bond is only going to end very soon.
