I don't understand this. What did you think was going to happen?
You two broke up and he has every right to flirt with other women. Doesn't matter that you two are still hanging out, because you are not in a relationship anymore.
Why did you even keep hanging out with him?
I know it hurts you, but objectively speaking, you have no right to meddle into his private life anymore.2
