EDIT....Is this innapropiate or not?

I clean a house for a young couple with a 5 year old.

Today, the wife was packing up to go out of town for a bridal weekend.

She leaves, and the husband comes home with the daughter and 3 of her friends. He said he has them for the weekends, which should be fun and asks if I want to stay. I don't remember if he said "stay over" or just stay.

Anyways, I pretend I didn't hear, and he talks a little more than mentions makeovers and again asks if I want to stay. I say I'm busy.

Once I'm ready to leave, he again asks if I'm sure I don't want to stay.

Mind you, innocent or not, I have an AMAZING husband, and I would never want to do anything that would give anyone the wrong impression. I'm also very attractive and get hit constantly, and I can feel he kinda likes me and likes to talk to me.

It's just a feeling, though, but I'm rarely wrong since I get hit on a lot.

Am I just misinterpreting, and maybe he just needed babysitter help? I highly doubt he would've asked this if his wife wasn't out of town. And I sure as heck know, she wouldn't be ok with me just hanging out when she's away.

I don't have small children, so is this common? Is it totally normal to invite people on playdates? Or maybe he just needed a hand, and I'm being cray-cray?

I already told my husband, so I'm not keeping this from him. EDIT: I think you guys are right, and I read it wrong. He was actually super happy, had a ton of activities planned. He was not stressed or in distress like many thought, he was saying he gets a Europe trip with the guys in February for this. I just have very firm boundaries for myself. Just the way it was pushed after I said no multiple times and my gut feeling. I don't think it's necessary to bring it up to his wife and seem paranoid and like I'm trying to cause trouble.
