Did I do the right thing?

Ok, the day before yesterday, i talked to one of my good friends. We are really close, and i have no problem with that.My problem is this, about 6 months ago, I broke up with my ex, and he is creeping me out. His mom orderd him to stay way from me, but I could care less. N E ways, this year, he is trying to get me in trouble by telling my current bf that im cheating on him, and telling our princapal that im talking to him, and he even went to my mom, and told he crap, also that he he still has feelings for me. creepy, or what? Weather you belive him or me, is up to you. But my quistion is, the other night when I was talking to my good friend, she asked me if I was cheating on my current bf, adn i set her straight, and she told me that my ex was over at her house.(he's dating her cousin-wich I already knew) and so I said ok, well i'm ganna go now. Then I rememberd that I never told her i wasn't cheating on my bf, so i texted her a said this " no i'm not cheating on so and so, and i'm happy for my ex" I'm happy he has a new gf, maybe he can get me off his mind. Then she lets him text me, and he says" if you awant to be firends, then take back everything bad you ever said about me, and i'll think aboutit. untill then i say no to being friends." When I don't even want to be his friend. Now keep in mind, i'm not even sposed to talk to him, as he to me. So I texed my friend sayg, i'm ganna go i can't talk to him. and she says y not? And i simply stated, because, i want nothing to do with him, and i don't want to talk to him, ganna go talk to my current bf now. bye." so did i do anything wrong, other than texting with out permissin? I just want to make sure so none of this blows up in my face, adn should I tell my conciler st school, b/cuz i'm sposed to be letting her know of any incounters with my ex, but i just don't want it looking like i made this up, as i deledted every message.
