Zara:
Yes, I would, if she were receptive in the slightest. On the other 
hand, if I feared losing her and thought the subject of Lupin annoyed 
her, I might not, but I would not describe such an omission 
as "distancing" myself from her. We have evidence that Snape did talk 
to Lily about his suspicions regarding Lupin, and that his previous 
remarks to her on the subject were not well received. 

> DH: 
> "I know your theory," said Lily, and she sounded cold.

Zara:
From this, I would conclude that he has mentioned Lupin and his 
reasons for suspecting Lupin is a werewolf. And that she has flatly 
refused to believe him, and has expressed annoyance at the topic, in 
the past. For evidence that Snape fears losing her...in this same 
conversation he asks if they are still best friends.
