First of all, you never should feel guilty about loving someone. There are no rules about who is supposed to love whom. The more love there is in the world, the better. You feel guilty because you are sexually attracted to him. But believe me, that doesn't make your love for him in any way dirty or inappropriate. If all you were feeling was lust, you would just want to jump his bones and not care about him as a person. I can tell from your posts that you care very much for him. And that's sincere love, my friend. It makes no difference at all that it's coming from a pedophile. It's still sincere love and something you should thank God for, not be ashamed of.

As for what to talk about, it's hard to give any suggestions without knowing both of you more. If you don't have a lot of social skills, she will probably understand that, so don't try to force it. And as far as how to ask if you can correspond with the boy, I think the direct approach would be best. Just ask. You don't have to explain why. The reason should be obvious, because you like her kid. Hopefully, she won't be the paranoid type. But if she is, there is no magic way of asking to make her less paranoid. So you might as well just come out and ask.
