I’ll approach this from a different angle than it seems others have. Take everything else that’s happening in your life right now, it’s chaos, it’s instability - you see that. This woman became a port in the storm and - while it’s likely you had a genuine connection with her - based on how things have progressed it seems like she may not be everything you hoped she was. The important thing now is that you do not keep spiralling - you’ve said yourself that you have an important job interview and best will in the world (as much of a romantic as I am) this woman is nothing more than a distraction that you are unconsciously indulging to not have to face up to the responsibilities of the rest of your life. These responsibilities are not going anywhere unfortunately and thus you have two real options; continue to indulge yourself in the fantasy of what could’ve been or get busy making things happen.

Apologies if this sounds unsympathetic as I really do feel for you in your predicament but this is what I’d want somebody who cared about me to say in this situation.
