My dd, who's 17, broke up with her (first) boyfriend last Friday. I liked him very much and was sorry that she felt it was time to end the relationship. Her reasons for doing so were solid. Anyway, he came by the house with some flowers for her, hoping to convince her to change her mind but when she didn't, he was very angry. He blamed her for her unhappiness in the relationship; accepting none of the blame himself. I was in my room so I heard him slam the door on his way out.
Since then, he's been telling mutual friends how terrible she is, which I guess is par for the course since he's obviously immature (he's 18). But now, he's making comments about her body, specifically her "lady garden" and how it hasn't been "tended". Not that he would know, as DD is still a virgin but that's beside the point.
How do I react? Do I call him and tell him to shut his fucking filthy mouth? I wish I could.
