Please Help. I've just learned this week that my big brother is cheating on his wife. He's unrepentant, wants to continue the illicit affair & wants me to keep silent. We've always been great pals, & he's been my hero since we were small (I'm now in my mid 30's he's 41). It's incomprehensible to me that he'd even contemplate such a thing, his wife is a darling & so are their 2 kids. It'd devastate the family if this got out but, dammit, he's in the *wrong* & I'm feeling sick.
