He's still friends with his ex on facebook. Should I tell him that it bothers me?

Anonymous
I'm dating this guy and he's still friends with his ex on facebook. I don't know how often they talk over the phone, but he did call her a "pseudo-friend" and a whore. He also said it's awkward that he still keeps in contact with her because he's not friends with any of his other exes (so obviously it was her idea to stay friends).

Now to the point...every time he makes a post of facebook, she "likes" it and it really makes me jealous and annoyed. Should I let him know that this or try to ignore it? I don't wanna make a big deal out of it. I trust him, but she just annoys me.

His ex is in a relationship with someone else and she's moving in with him in December. And from what he tells me, I don't think he wants to get back with her 'cause she sounds crazy.
