<human>: Condense the text into a few key points

He's still living here and in less than a month he will be gone, never to be seen again or so thats what hes told me.

However, he isnt hostile in the slightest. In fact, at moments he looks regretful, before quickly reminding me about bills and belongings he needs to sort out before he leaves. He offers to make me dinner, asks to spend time together watching a movie, things like that. Hes asked about my career plans (as Ive been unhappy at work and considering finding a new job).

Not much as happened between us, or nothing big enough to cause a breakup. He's dealing with a ton of personal issues relating to death in the family including remorse and guilt. 

My approach has been to completely back off, stop crying and pleading with him. I know I need to let him go, but I dont think it will bring him the happiness he thinks it will, because I didnt cause his problems. Could I have been more patient with his moods? Yeah sure. But I didnt cause his issues and I cant fix them for the same reason.

Can someone please offer some kind of idea as to why he is on one breath pushing me away and on the next talking to me like nothing has happened? Will he regret leaving when his emotions have calmed down? Does he just need space to deal with things on his own?
<bot>: broken up, still living together, his mind seems to be all over the place. with a bit of space and time after he leaves, do you think we can salvage this relationship? What would you do?
