What do you do if you are being subjected to some or all of the above? Find the courage to leave as soon as possible and close the door tightly. Manipulators (who could also be undiagnosed sociopaths or narcissists) will likely never change and you will continue to enable their behaviour by accepting what they dish out. The price to pay will be your self-esteem, your identity and you will learn that your needs are not important.
Once they are gone, even if they were the one who did the discarding, it is important to know that unless action is taken, they will never really be gone. They will always reserve the right to come back and tap into their ‘supply’ again, creating chaos all over again.
If it was a bad break-up, that is that one partner was surprised or there was a general lack of communication and respect, then the process can be extremely traumatic for all concerned. How you handle it afterwards will largely depend on you as an individual, your coping mechanisms and your willingness to move forward.
I have realised that building a golden cage is no guarantee that the person inside it is going to be happy being there and may want to spread their wings at times. I have also hurt others with my codependency and my expectations of them.
