Is my 40-year-old former manager actually crushing on me at 26?

She is too playful around me, I left the company, and we only met once ( we were setup in other countries)
But when I left my job I went to meet her, I got her WhatsApp number.
And I have shifted to the same country for my higher education.
And we share too stupid stuff,
She doesn't hide her inner child in front of me.
