A Conversation - Are Threesomes Okay?

So, a woman asked me out on a date last week. We are scheduled to go out tonight. After getting home from an interview today, I get this text from her --

Woman: "So, do you have any idea where you'd like to go tonight for our date?"
Lauren: "No, but I can figure it out if you can't."
Woman: "I'll have my husband figure it out."
I close my phone absentmindedly. What the hell is this chick talking about? Does it look like I want a freakin' threesome? Hell to da naw. I stare into the distance and before I know it, three long minutes go by as I figure out if I want to cancel the date or not.
Lauren: "Wait, you have a husband?"
Woman: "No. I'm kidding about the husband, momma. I have to get back to work. Talk to you later tonight."

Hmm, something told me she isn't kidding. Who the hell kids around about having a husband? No one...oh, unless ya got a husband, right?

I asked my friend what she thinks and she agrees. Says I should cancel the date. So, I send her a text back --
Lauren: "I can't make it tonight. Have a good day."

I definitely don't regret being honest, which saved me time in the long run and potential drama.

But, I'd love to know...what would you have done?
