Thoughts?

What are the questions you ask when your a new mommy and your baby daddy/ex has a new girl eventually ? What do I ask her never gone through this in terms of this is my first child and me and the baby father are no longer together and he’s the type to be a man hoe and have a new boo so quick to make me jealous. Which tbh I am doing amazing without him and really don’t care so it’s like he’s wasting his time and it’s sad he has not grown up yet .
