Help with my new room mate!!?

im living in madrid atm but going home in a week (finally!). A new room mate has just moved into my flat and it's just the 2 of us. She's a 29-year old with a good job and came from barcelona to be with her boyfriend but then she cheated on him and he dumped her, hence her living here. Anyway she seems really down about the whole thing and told me she'd rather die than live...but I have found that spanish girls can be dramatic and obsessed when it comes to their bfs, so i dno how true this is. Now I feel like I can't leave her a alone and dread coming home to what i might find. She always asks if she can sit with me but doesn't want to do anything, so we just sit there in silence. I know it sounds selfish but I want to enjoy my last week here, and now I'm petrified of saying or doing the wrong thing with this girl even though I barely even know her.
