I do feel sorry for Michelle. She has this whole media image of being a hearbreaker, marriage splitter but none of us know how far from teh 'real' Michelle that is. Perhaps her relationship with her husband was dire, perhaps she just wanted out of the relationship.
Her Ex has sold his story to so many magazines, certainly more than she has, as the wronged man - yet there is no evidence at all that she had an affair, only the stuff he says which I don't think can be relied on.
I think she is terrified that the press will twist stuff and make things uncomfortable for her boyfriend who she seems to really love.
Coolio is quite intimidating and I think having him constantly make an issue of her and ben's relationship when she is feeling this worried about the media already is not fair. Though of course maybe she shouldn't have put herself into that position (Ie become a housemate) in the first place.
I think Michelle is fairly articulate, very led by her emotions... Having been through a break-up myself (I left) I totally sympathise with how fragile she might be feeling and I think it's clear that Coolio was being very awful for a long tim.
