I wouldn't give this guy the time or attention he's so desperately seeking..
Why it would be affective is that he's acting inappropriate and creepy and the problem with abusive people is that they do so behind closed doors. Open the door and expose him. He'll quiet down really fast if he gets a phone call from his mom about it.
I would not talk to him anymore at all. Tell him you get it--- he's done you wrong and you are not interested in any contact with him anymore. Then continue your therapy to explore it further if you so desire. He's given you all you need to know and frankly, he sounds like a whack job. anything else he says could be unreliable.
BTW: if he molested you, don't you fear that he could molest someone as an adult? Exposure of that is good thing. I'd really consider telling someone in his family. good luck
The problem with telling his parents is that they don't really care about what he does. He has been through a lot in his childhood (witnessed many of those things on him and his siblings).
I do fear that he might do molest someone else if he did molest me, but while talking to him before he told me that he did something signalizes in some way that he's sorry about it. Every time I ask him to tell me, he always answers with "I'm not ready yet." or "Don't you think I need some time to process this?"
Wow! You really shouldn't be feeling guilt over how HE feels! He should have"processed" it before he brought it up to you! This just reinforces the reasons that I am so protective of my girls! Its not just grown men but also teenage boys that rape and molest... I am sorry you are going through this but I honestly don't think you should feel bad for him.. He also shouldn't feel free to do this to others. How old is this guy? I think you are prolonging your misery even by letting him speak!
P.s I'm sure that a phone call from his parents or even his sister that you were friends with would stop his stupid attention attempt! Its very twisted! Don't give that ****** any power!
The way he is toying with you suggests he is a little bit nutso. Eliminate him from your life. If he is responsible for a bad experience (and it is not clear that he is) it has apparently not affected you. Keeping up a friendship with him will affect you. Be done with him. He is unhealthy.
