Things that happened years ago and never bothered me before have started keeping me up at night since having DC. They relate to family we still see and are on good terms with.
I go over and over it and wish I'd asserted myself more at the time, even though at the time I just wanted to smooth things over and move on as soon as possible. My DH, who saw first hand, insists it was emotional abuse although I'm still not sure if really was that extreme. I did have a controlling ex when I was younger who tried to isolate me from my friends and family, spread lies etc, which had a lasting effect on my friendship circle and relationships, and I recognise that but I don't feel angry about it now and have moved on from it. But now again I'm up and can't sleep feeling upset about family matters that happened years ago. It makes no sense to bring it up now though I'm sure and would cause a needless rift. So how do I forget so I can get some sleep?
I wouldn't ever let DC be made to feel the same way, but it's definitely been revisited in my mind since them.
