our un-relationship

[Dom R]

here's the thing.

you miss him.

he misses you (that's GREAT! you're so lucky!!!)

After a year of positive living life together... maybe it's time to tell him that.

Tell him that you'd like to "connecting together".
Remind him, that in the normal world (as opposed to his odd universe ) that is usually considered "what boyfriends and girlfriends do".

So, you would like him to treat you like a public girlfriend, rather than a closet girlfriend. and stop treating other people like one. you want to be his ONLY "girlfriend."

Yes, that DOES mean changing his behaviour with others.
Ideally, it will mean that he completely stops seeing those other tarts.

Yes, he's going to miss them.
but if he enjoys being with you as much as he says he does, then he should be able to choose being with you, as someone that makes him happier. rather than a fake romantic fantasy fling

You had a really nice way of putting what you said, in your first draft. maybe you can come up with a good way of putting this in your own words, that he will find appealing.
