At this point, I would guess that your employment is now about the merits of your work performance and less about filling in for her, so to speak. Does one truly owe another a daily friendship or whatever level of friendship over a good reference/referral?

And about the other part about giving her an inside track to your bf. No. Just, No. Granted he's not some piece of property or a piece of meat. No. Gosh that's about the most awkward request. :\
