BlueCrustacean,
I am sorry to hear that you're feeling so miserable because of your parent's relationship. I am sure that it was a difficult experience. Did you not see any healthy relationships, to refer to, as you were growing up? Maybe friends or extended family (cousins or grandparents)?
Have you tried reading any books to help you understand yourself? You may want to try looking into it at a local library. Or, maybe even online. What is it about divorce that sort of thrills you into fantasizing more about it? You don't have to answer...just something to think about. Perhaps you could also try writing about your experiences. Just getting your thoughts & fantasies out on paper can help reduce ongoing thoughts about it.
As you know, we aren't therapists here, at Psych Central. We're merely peers trying to help one another. I'm sorry that you aren't happy with the responses that you've gotten on this thread so far.

There are only so many ideas that we can come up with to help relieve you of your problems. There are a whole lot of ways that you can make this an ongoing issue in your life, but we certainly don't think that would help.
Therapy. Reading books and checking out workbooks to help. Talking with friends or relatives about issues that haunt you. ~ Those are the only ideas that I have to help. Sorry if it's not enough.
