thats how i feel. Its nice to get it out in the open without discussing it with people who know her...
seriousely though, after 8 years, she deserves your love and support no matter what. Be there for her, thats what she needs. Let her know something that you may be hiding or feel weird about.
If you handle this right you could end up being closer with her! and even though people laugh, there are much weirder things out there than a MJ obsession!
