Is it normal to shit talk exes or does that mean ur not over them?

My boyfriend showed me a pic of his ex and I said he got an upgrade and he DIEDDD laughing again and again and told all his friends. Highly tho I am sexy asf. I told him I regret saying that and that all girls have their own beauty. But he loved that I shit talked his ex. I would be kinda salty if my boyfriend shit talked my ex bc he doesn't deserve to be bullied.
