I’m going through the exact same thing @fruity12 and it’s so hard when you love someone but you know they’re not right for you. Well for recognising that and acting on it, that’s almost the easy bit - the hardest bit is getting on with life afterwards, especially if he’s promising you the world.
Just keep replaying the horrid arguments instead of the nice bits, remember how he made you feel when he spoke to you like that. That you no doubt told him repeatedly that you wouldn’t accept that behaviour and he carried on anyway.
I tried counselling with my verbally abusive partner but he just used things that were said as ammunition in our next arguments and never really changed in any meaningful way because he never accepted he had done anything wrong. Or he twisted what the counsellor said to fit his narrative.
I go to counselling on my own now and she said it’s like an addiction and you have to go cold turkey. Every time you go back for another hit you send yourself back to square one and have to deal with the withdrawal all over again.
Texting and looking at photos is methodone/nicorette - it’s keeping you addicted to the good feelings not cutting you off from them.
At a later point you can start to reminisce about happy times, but for now try to focus on the reasons you split.
Is there any way you can get your stuff together and store it elsewhere to save tou keep going over there?
I know how painful this is for you but no contact is the best way, even if for a few weeks to break the pattern of addiction. Then when you speak to him after that the magic will have faded.
Is he your little one’s dad? If you need to keep in contact for them you need to keep it brief, focused on the child and emotion free.
