I have a little folder too with photos of bruises. Smashed doors, my car windows broken, me crying.
Keep them incase you ever need them, but maybe move them to a different folder to prevent you seeing them accidentally? I have an iPhone so moved mine to the “hidden”folder.
You are going through a withdrawal - do some reading on trauma bonds if you can.
Its hard, you are going cold turkey, you crave the “hit” of everything being ok again. You feel ashamed, question your own judgement but none of this is on you - the abuse is like a dripping tap and you don’t realise what you went through until you’re out. Your feelings right now are normal and healthy and they WILL pass.
You must never go back to this man - leaving is the easy part in a way, it’s staying away that is hard. One day at a time, just small steps.
My ex was vile to me, I’m nodding along to things you’ve written because they are so similar to what I went though. He went to work one day and ghosted me, and was then in a new relationship within a week.
7 weeks later he was begging to come back. If yours does the same please do not let him, you can’t heal in the presence of those who hurt you.
