Such a complex word.
Here’s what it looks like to me …
My former husband was in love with himself. His needs, desires, and wants came before all else. I thought if I did everything he wanted, I’d make him happy. I believed if I agreed with his every comment and wish, only then would I have some measure of peace. I figured if I made the peace in letting him have his way with me, then surely he’d show me tenderness and love, preferring me over his need for others – hobbies, friends, or conquests. But I was merely fooling myself. I received no respect and he continued his ill-treatment toward me. Silently, I resented what he was doing to me, but not enough to do anything different. By me allowing the offenses, I was giving him permission to continue to do me wrong, as if I signed all my rights and life away. I was slowly dying inside. I felt undone, and unloved, with a low-self esteem and zero self-worth. I felt lonelier with him than without him. Yet I still wanted him around. As I yearned for his approval and acceptance, I lived in constant fear of him and lived with the fear of losing him.
We think if we can control our environment, we will find peace and tranquility. But in reality, serenity is usually miles away. You might have a false sense of peace and trust me when I say it isn’t lasting. And oh, the price it comes with!
I’m no psychologist, nor am I a psychiatrist. But I also think there’s another side to this spectrum. Sometimes a person may love so much and love so deeply that they tend to do everything for another, thereby potentially stagnating and handicapping that loved one from doing anything for themselves. That person then becomes dependent on you for their needs and outlook in life. They are hindered from growth and maturity in making wise decisions or choices. They are emotionally immature and can remain psychologically traumatized.
Such as in the situation with my mom. From her childhood early on, Mama was introvert and extremely shy. Grandma loved her so much that she felt sorry for her. She tended to overcompensate in trying to help Mama by doing everything for her. Mama naturally grew dependent on others to do things for her all of her life. Then in my early years, I tried looking out for Mama and did everything I could in trying to protect her. Most of the time my help was unwarranted, as she sought and relied on her significant others to fulfill that need.
So, co-dependency can be a vicious circle and left untreated can fester like a sore that won’t go away.
