That’s an entirely predictable response, and a common one.
I have said this often, but one of the things about relationships ending ( am aware it’s not straightforward) is that although it may be over in the sense you are now living apart, the relationship dynamic continues. He wants:needs you to look after him, and to a certain extent you want/need to continue doing so. It’s not unusual, it can even happen in abusive relationships.
It’s why in my opinion it’s really important to actually have a real break for a period of time to allow you to reset. Otherwise he may not be in your house anymore but he’s constantly in your head. If you can get him out of your head, that will give you the mental as well as physical space you need. It will help you to get the distance required to actually really understand what you have been through, and more importantly what you want going forward. It’s difficult, especially when you still love him, but I genuinely think it will be the best thing for him too. And all of the DC. It’s time for you all adjust to the new situation ( especially the DC ) with no muddying of the waters. He has to accept his new reality, and make it work. As you already are.
That doesn’t mean necessarily the end of any relationship. But it means that any future relationship as either lovers, or indeed just friends will be a new, and different one, not simply the old one in different households.
As I said this is the more difficult choice, it’s easier to keep in touch. It may be less painful to continue as you are, but you are possibly just postponing the pain. Better to feel that pain, grieve for the loss of the relationship now . And far better to allow yourself the headspace needed to bring you clarity you need.
