I'm choosing to respond to this message here because it's the top one. A lot has happened in the last couple hours.
First, to respond directly to you- I make no excuses for him. I am not covering for him and I am disgusted by his actions. I had similar things happen to me at 14, so this is nothing short of repulsive to me.
When I came home from work, I made sure to gather any additional evidence (facebook messages, text messages) nothing very concrete.. but all innapropriate. I then reached out to the brother-- Who I then immediately convinced to talk to parents. I had no other way to directly contact the parents; as both the girl, the brother, and the parents all live in another state, and I really didn't know what else to do to get ahold of them. I was never really worried about the brother (because of distance) showing up with a baseball bat-- but that's not that I think he wouldn't deserve it. I love Erik, but this shit is... unnaceptable.
The parents requested I send them any evidence I had, and I did, though I believe they are still reviewing their legal options and what they want to do. I'm not sure what they will decide, though I stand by any decision they make. When I had something similar happen to me, at the time, we decided not to pursue it legally but I'm glad my mother knew (in hindsight) because she put a stop to it. I feel much better knowing his parents know. I know they've talked to their daughter, and both me and the brother and my other roommate sat down with Erik to talk to him about... how.. un OK this all is.
In the meantime, I'm still deciding what to do with Erik personally. He's removed the girls phone number, facebook, skype and sworn all communication off, though none of that really reassures me. No rational adult would do this in the first place so I'm inclined to not believe him. I told him I had proof of his actions, that I was dissapointed, and that the parents wanted him to call them tomorrow and that he'd be a damn fool to ignore it. I don't feel comfortable with him being here. If the parents decide not to have him arrested/registered (which I don't know if I agree with- but I'll support their decisions) I am unsure if I can allow him to live with me. I told him he very well may have to move back home, because right now I can't stand looking at him, let alone letting him be here.
