Some dude called my cell phone looking for my fiance

So, it sounds like your intuition was right at the time (i.e. this is *bad*).

That said, I would have tried to be calmer after she hung up. You're engaged, have a daughter, etc. There's always an outside chance that there's a reasonable explanation. If there's a good explanation, it's way better to find it out before the yelling and screaming starts. If there's not a reasonable explanation, well, putting off the foaming-at-the-mouth anger for 5 minutes is just fine.

I'm sorry if this turned out as bad as it sounds.
