Is this flirting ?!

Wondering if this is flirting? Husband just got caught less than a month ago about to cheat on me with a 19 year old… he’s 36…. She messaged me about it. We are separating but he says he is “trying” and going to therapy bc he doesn’t want to separate. Just found this on his insta and feels like he’s flirting and fishing for someone else. Am I emotional still? Or is he pushing it?!
