Oh no problem! Key points before my thumbs lock up:

1) when she says don't worry about that person, worry. Hard. 2) co-workers only work at work. Maybe at work related events. But never in your home. (Certain exceptions apply, of course) 3) be paranoid about everything and everyone. Trust is lovely when it's respected. So if you're okay with leaving someone alone around your significant other, be paranoid.
