I don't want to step into your personal life, but does your mom know what happened? Maybe the two of you could work together in avoiding and keeping away from him - you could change your number (if you haven't tried that already) and if he tries to get information from her she can deflect him away. I'm so, so sorry you have to deal with this, and I hope you and the people you love are safe from him.
I don't mind these questions. I was actually going to include this in the post, but it was long enough as it was, so I took it out. She doesn't know. She knows that he's made inappropriate remarks about me, and she knows that he has touched me in ways that I deem inappropriate, but I will never tell her anything more than that, for her own sake. As for changing numbers, I wasn't going to worry about it because I managed to go almost this whole year without hearing from him, but now that he's cropping back up again, I'm going to be looking to see if I can get a number change. I have one of those store phone though lol so I don't know if I'll be able to. And as for him trying to get information from her, she knows that I want nothing to do with him. And whenever he tries to milk her for info or get her to make me call him, you know, that, "Why won't she call me back? Tell her to call me," shit, she just tells him, "John, I'm not Alex. I can't tell you why she isn't calling you back. And I can't make her do anything." My mama is awesome. :) And thank you. Really the only person from my family who he can do damage to is my mom. She's the only one whom he knows where she lives, but he can't get to her since he isn't allowed to drive. I told her I'm worried that he'll do something, though, and she just laughed. "What is that boy going to do to me?" Which made me feel better, but worse. But she's not one to stand for bullshit, especially not his. And if he tries anything, I will put his ass in a hospital if not 6 feet under.
