I don't really know enough details and I don't want to be nosey, but in what capacity are you 'moved back in'?

Same bedroom? Or not? Do you spend time together when you are both not at work? Is he trying to?

I think (just IMO) that if he had NO feelings then why would he want you around at all? It is sometimes hard for guys (and girls!) to retract things they say out of hurt, too. Sometimes it is better shown.

I had an ex bf who had ... well shall we say I drove him a little batty when we had arguments. I always try and over explain, over apologise. It is funny and sounds weird but when he had got over whatever it might be (he is a space-needer, I am a push-to-sort-it-out type - not very compatible) he would send me something like a pxt of his doggie ... or something else he'd seen he liked ... once it was lil ducks he saw on a walk.

For a hard house / hard trance DJ who is a bit of a boys boy, it might sound weird ... but he could never say ok i accept your apology. It was always something like a pxt instead. Strange, but true ...

But it sounds like you guys have a bit to get through ... do you think it's the best place (his) for you to be right now? Sometimes space is better than trying too hard.

I dunno, just my-.0002 cents ... good luck ...
