I'll try to keep this short.
When I was a teenager, my mum had an affair and left. Even though I was relatively young, I still knew before she left that she was having an affair.
I didn't speak to her for four years - completely out of my own choice, my family were always supportive of whichever choice I made, and it was left completely up to me.
When we got back in contact, it was alright - not perfect, and certainly not a close mother-daughter relationship, but we just didn't talk about what she'd done and chatted about other things instead.
(Just as an aside - my DSis - who I love to bits - has had a few problems with depression etc. over the years, so me and DP have looked after our DNieces for extended periods of time; I really feel like they are my extra daughters.)
My youngest DN is just coming up to the age that I was when my mum left, and I still cannot get my head around how she could have just left us.
There was no DV going on - my dad was just as shocked as the rest of us when she went.
I'd appreciate some words of advice, please. I don't know how to get over this. :(
