Everyone has broken a boundary and has had boundaries ignored. This can cause injury. However, it is not always clear when the boundary is broken, stretch, or miscommunicated. Sometimes injury occurs due to personality or just not getting along. When you don't like someone, it takes more effort to respect boundaries. Sin will always interfere with boundaries if you allow it.
Good and mature relationships can still be hurt when boundaries are withdrawn. It takes practice in dealing with disagreements. It takes learning skills not to hurt people when you are angry. Withdrawing is hurtful. It is fine to walk away for a little while to calm down, but never go to bed angry or still withdrawn. It only hurts the relationship more.
When you allow anger to become a part of you, then hostility invades boundaries. It is always painful. Everyone has disagreements, disobey, and disrespectful habits. These have to be broken. You have to learn how to delay gratification to become a responsible and respectable adult. You also have to look for the blessings because they may not be what you want, but what you need. Do not allow impatience to lead you to cause boundary injuries.
On the other hand, trying to control every aspect of life is just as dangerous. When you try to control another person you may be unknowingly causing boundary injuries. Don't be too strict or limiting another's life. It will always cause resentment or worse.
Lack of limits can cause boundary injuries. This is allowing anything to try to keep the peace. You have to risk an argument or two to have a voice. God does not bless the pushover. There is a difference between being a peacekeeper and a peace maker. A peace maker knows that they have to say and back up hard truths for the greater good. A peacekeeper will stay silent to avoid conflict. There is a difference between being a push over and being meek. A push over has no boundaries and reveals weakness. A meek person is strong because they have self-control, humility, gentleness, and know how to submit when it is time to submit.
You need to be consistent with your boundaries. When people are pushing back it can be hard because they wear you down. You get tired and it is hard to stay firm, but if you don't then it makes things confusing. It sends conflicting messages. You have needs and you need to fight for them.
Trauma can mess with the head. Trauma caused by another person can leave serious distrust issues in a person. This is a major violation of boundaries. Emotional, physical, sexual, and spiritual abuse (church leaders taking advantage of their position) will cause trauma. Trauma can affect a person for the rest of their life. God can heal anything, but there will always be scars. Other trauma could be a debilitating illness, death of a loved one, divorce, or anything that causes intense pain. It will affect your ability to develop boundaries. It is your responsibility to work through them though. Do not stay a victim your whole life.
