He sounds really still preoccupied with her (gee, you think)? I am not sure why, but he's obviously not over her. She sounds like a terrible person, I can't think of what the attraction would be.
Good luck with everything. As far as hard-core porn sites, I've wandered on by accident - often they are very close to normal website addresses. IMHO, they are disgusting and you don't want to be emulating them. I am sure I've not come close to seeing the worst. Don't do things that aren't comfortable to you. Maybe Monster does really gross things as far as writing and other stuff, but don't do it because she does!
