Codependent relationships are thus constructed around an inequity of power that promotes the needs of the taker, leaving the giver to keep on giving often at the sacrifice of themselves. According to Dr. Mayfield and Dr. Exelbert, signs of codependency might include some, but not necessarily all, the following:
A sense of “walking on eggshells” to avoid conflict with the other person.
Feeling the need to check in with the other person and/or ask permission to do daily tasks.
Often being the one who apologizes—even if you have done nothing wrong.
Feeling sorry for the other person even when they hurt you.
Regularly trying to change or rescue troubled, addicted, or under-functioning people whose problems go beyond one person's ability to fix them.
Doing anything for the other person, even if it makes you feel uncomfortable.
Putting the other person on a pedestal despite the fact that they don’t merit this position.
A need for other people to like you in order to feel good about yourself.
Struggling to find any time for yourself, especially if your free time consistently goes to the other person.
Feeling as if you’ve lost a sense of yourself or within the relationship.
Co-dependency is not ONLY characterised by spending a lot of time together. Couples CAN spend time together and not be co-dependent. Spending your time with/on your partner is on the list but it is more than that one thing. Couples can spend little time together and be co-dependent. This conversation could be a lot more interesting and informative than just throwing insults around.
