AITA for blocking a mom after a play date because she said she wants to marry her son?

AITA for cancelling a play date because a mom said wants to marry her son?

I really need advice please help

Hi I’m a mom of 2 boys age 3 & 2 and I had a playdate with another mom who has a daughter age 4 and a son age 2

I joined a mom group in my city and had a playdate date at the park because i didn’t know this lady to have her in my house or to go to her house.

Our kids were playing well and we started talking about what schools they would go to and how we thought they would do in the future.

I told her i can’t wait to meet who they’ll bring home or if theyll ever want to bring someone home and the type of future MIL I’d wanna be.

I only have boys so if my kids are hetero and i ever get blessed with a daughter in law I’d probably spoil her.

Anyway as we were talking she said not me If i could I’d have him marry me and stay little forever

I laughed a little because i thought she was joking and it was awkward but know she doubled down and said it’s something about having a son with this weird look on her face. She said some other stuff that was weird now that i think about it.

My son started to get hungry so we left and she messaged me on the mom group and said she was sad she didn’t get any pics of the kids playing and wants to plan another play date. I blocked her.

I told another mom that i know what happened and she said blocking her was harsh because it kicked her out of the FB group we are in. But being around her freaks me out. I always saw posts about boy moms but never seen it in real time.

Please give advice because now i feel bad

Edit to add some of the stuff she said/ did that i thought were weird

She ignored her daughter and got her in trouble for playing. She wanted to do cart wheels and her mom said she needed to sit down

She said she wasn’t ready to potty train her son because then he wouldn’t need her as much

Said she would take my son to the potty for me. ( i just met her)

Said daughters are so much harder than sons within earshot of her daughter
