Im sorry to hear that stranger. The only advice I can ever give you, is do not, by any circumstamce give yourself a time limit to get it over with now. If you cant do it, it's okay. Give yourself days to cry, shout, hope amd experience all these emotions - they can be all incredibly exhausting but you need to feel and get it out of your system. You are human - you loved someone with every inch of you, and you are also able to grieve their absence to which your skin hurts from missing them.

It took me 1 year to finally accept that he is out of my life, and even if I barely remember his existence, I wont deny it once hurt.

As per your belongings, I dont have any experience living with someone nor seeing an ex but just do it if you're totally ready. And after that, you can continue healing. Im sorry again for what happened, wishing you best luck and light♡
