That's probably a good idea, just to delete him, but to be honest because he has phone numbers he may just talk more shit about how "Oh yeah she deleted me, what a (Insert profanity), she such a (insert profanity)." That's usually how it goes. So that could also cause more drama, also the idea of being "immature" Which- I don't see how deleting someone off facebook resorts in immaturity, but this happened to my sister awhile ago with an ec boyfriend who would harass her and be rude to her so she deleted him and he texted her rude things about how she did that. She was being "immature"

But- "Every action has an opposite and equal reaction" So no matter what you've just got to do what you think is right.
If shit hits the fan, just know you made the right choice. :3
