I dont know whether this is in anyway useful or not (I hope it is) but I was in this exact position 2 years ago. I lived with my ex and one evening while I was in bed he just disappeared (I've posted about this before) I was absolutely heartbroken and devastated, I didnt think I would ever get over him. I cried constantly, felt absolutely broken. I messaged him, emailed him and called him thousands of times! I begged him to talk to me, sent him essays etc. He completely ignored me but he eventually contacted me a few months later and I let him back, he messed me around for one year and it ended with me falling pregnant last year (I had a termination, my ex was physically and emotionally abusive) and I have now not seen him since May 2019 or heard from him since December 2019.
Now... I feel nothing. I dont hate him, I don't love him. I genuinely feel nothing for him and it is so liberating! I never ever thought I would be in a place where I would ignore him if he contacted me. I thought I would be stuck in a limbo, always waiting around for him and I thought I'd be an anomaly - the person who never moves on!
It is hard, so so hard. But time really is the best healer. I also found keeping myself busy and distracted helped a lot. I went on quite a few dates but that probably wasn't a good idea as I'd get too upset thinking of my ex and comparing everyone to him, it was just to fill a void. I worked on myself a lot, started new hobbies and filled my life with things without him.
I have now met someone else and all of the pain and anguish feels like a distant memory!
I just wanted to say that you will all be okay. Put yourself first and look after yourself, allow yourselves to accept and feel all the new waves of emotions! Get stuck into a box set which absolutely does not remind you of them, go for walks, have a bubble bath, order a take away. It will get better.
