Firstly happy new year all.
Secondly a bit of background - partner was cheating on me with OW and we split in 2018. had a horrible break up which involved him and her calling me on speaker phone with her hiding in the background while he hurled abuse at me. that was the last time we ever spoke. I had so much hatred for him getting over the affair was easy and I met someone else.
However the last month or two I have been having strange dreams where either him or his family randomly appear. He is still with OW and last night I had a dream someone in my family and her became friends! All of a sudden it is like I am remembering the very small nice gestures he did whereas before all I remembered was the abuse he gave me. Is this a stage of grief that is majorly delayed? I have also been thinking that I want an apology for him as he never sincerely apologised for everything he did - of course I will never get this in a million years but why nearly 2 years later is this stage of grief popping up? I might also add things with me and my partner are heading towards marriage so is this me trying to tie up the loose ends? I have no feelings for ex he is actually a very horrible nasty mean person but for some reason I have started to feel sympathy towards him and I don't know why.. or is this progressing towards a stage of forgiveness?
Before I was angry and hurt, then that diminished when I fell head over heels for my partner. Fast forward a year later and I now feel sympathy and the anger is almost gone but is Turning into something else and I don't know what... any advice?
